Powershop is New Zealand's newest and smartest power retailer. By 'power retailer' we mean we are responsible for the supply of electricity to our customer's homes & businesses, reading their meters and billing them. We supply electricity to residential and business customers in many parts of New Zealand and provide them with easy to understand information about their power usage. Powershop is the smarter way to buy power, offering customers flexibility and choice.
Powershop is wholly owned by Meridian Energy - a NZ Government owned State Owned Enterprise (SOE).
Powershop is headed by Ari Sargent, a well respected figure and innovator of the power industry with 20 years of experience, and a former executive of Meridian Energy.
We are a stand alone company, and operate independently with our own Board of Directors, including independent Chairman John Journée who is currently also Chief Executive of the Noel Leeming Group
Powershop has complete autonomy over who we do business with, we have our own wholesale energy trading operation and complete control over the products we sell and how we price our ‘Standard Power’ house brand products.
Not at the moment. To find out when we are able to supply you with gas please subscribe to our updates and we'll keep you posted. You can still switch to Powershop for your electricity supply and keep your gas with your existing gas supplier.
We offer our customers a range of power products, including some of New Zealand's best-priced power. You have the choice over the kind of power product you buy (i.e. the cheapest, the greenest, one associated with a charity).
Once you have switched you will be set up as a “set and forget” customer – you don’t have to do anything. We will purchase the power you need for you each month using the default product preference you set (e.g. the cheapest product) and charge it to your preferred payment method. Or you can do your own power shopping though our online shop where you can choose the kind power product you want to buy.
Powershop is the smarter way to buy power. Powershop is online, and we provide easy to understand information that allows our customers to understand how much power they are using and to help them use it wisely. We also offer customers choice about the power products they buy and the flexibility of when and how they pay for it.
You don't have to do anything differently if you don't want to. You can deal with Powershop in exactly the same way as you deal with your existing power company - where we take a meter reading and you pay for the power that you've used each month. If you want to take advantage of all that Powershop has to offer you can use our online shop where you can log in as often as you want, enter your meter readings, see how much power you're using and snap up our offers and specials.
No, you don't have to read your meter yourself. Our meter reader will still come to your house once a month (in most areas). We do suggest though that you do enter meter readings online on a regular basis so you can better understand and manage your power consumption.
We recommend you login at least once when you first become a customer and enter a meter reading. However the more regularly you log in and update your meter reading, the more you'll be able to see how much power you are using - no more bill shocks! You shouldn't need to spend more than 5-10 minutes a week to take advantage of all that Powershop has to offer.
Powershop has no plans as such. We're committed to offering you some of New Zealand's most competitive electricity prices so regardless of what kind of plan you may be on with your current power company, most customers can save with Powershop, simply because they’re not on the best tariff.
There are no additional fees or charges like daily fixed charges. The full cost of your power is included in your unit price. But we do charge fees for additional services in special situations, see our schedule of fees.
Everything required to supply power to your property. This includes the cost of the power, the lines charges, Electricity Commission levies, GST and other service costs such as meter lease and reading. Only additional services are not included in unit price.
Powershop wants to make it easy for our customers to choose the power products that suit their budget and lifestyle. We think daily fixed charges add confusion. Having just per unit prices is much simpler as it allows you to easily understand what you are buying and make ‘apples-for-apples’ comparisons across different kinds of power we offer in our shop.
Yes, you will be charged for additional services in special situations e.g. special meter reads you request - for more information see our schedule of fees. We will tell you if you are going to be charged.
No, this is already factored in to our product prices and your estimated savings. In most cases Powershop will still be cheaper than your existing supplier even with their prompt payment discount. Compare savings using our savings calculator.
Yes, if you use less than an average user- 8,000kWh (North Island) or 9,000kWh (South Island - South of Christchurch) per annum - and the property we are supplying is your primary residence (i.e. not a holiday home) then we will ensure your prices are no higher than an average user. To take advantage of this you must opt in. To update your account as a low user, login to your Powershop account, click “my settings” then “account preferences” click the tick box for “primary residence/low user pricing” and press Save Changes.
Yes, you will still get the benefit of your multiple meter set up with Powershop. Your prices are determined by the amount of your power use that is metered as controlled and/or night.
Your prices will be a ‘blend’ of day and night or controlled and uncontrolled rates that reflect your metered usage. The more night or controlled power you use the lower your prices will become.
Powershop is a competitive marketplace for power, where prices will rise and fall, and will be higher in some times of the year compared to others. However, the Powershop pricing commitment ensures that most customers will still save money across the course of the year even though our prices rise and fall from time to time.
Powershop, like most businesses, has fixed costs that are incurred irrespective of the number of units sold to a particular customer (for example to lease the metering equipment at a property). In addition, Powershop is charged daily charges by the lines companies which are payable whether a customer uses a little or a lot of power.
As the Powershop approach to pricing is to offer a single unit price to a customer that has to cover all costs, it becomes necessary to adjust (or scale) the amount of this charge that covers fixed costs, based upon how much a customer uses. So a low user will pay a similar amount per year towards the fixed costs as a high user.
So as an example, if Powershop’s fixed costs were say $200 per year, and we needed to recover this equally from a user who uses 5000 units per year and one who uses 20000 units per year, the component of the unit price for each user would be 200/5000 = 0.04 (4 cents) and 200/20000 = 0.01 (1 cent) respectively.
All other Powershop costs are variable costs. As such, these costs are recovered with no scaling based upon how much a customer uses.
So whilst it looks as though the low user is paying more per unit, they are not paying more towards the fixed costs and are paying the same towards the variable costs. This approach of scaling the unit price based upon how much someone uses simply ensures that all users are being fairly charged for their proportion of the fixed costs.
Prices will change from month to month, but they will always stay reasonable – we're determined to save our customers money and our commitment is to always bring you some of New Zealand’s most competitive electricity deals.
The cost of your power will differ depending on where you live, your metering set-up and how much the lines company in your area charges. If you have more than one meter, you will generally have cheaper power prices as a multiple meter set up means your power company can take advantage of off-peak times and are able to pass these savings on to you.
Powershop prices per unit include all daily fixed charges, whereas your current power company’s price per unit will almost certainly be in addition to a daily fixed charge. We reckon daily fixed charges are confusing. Our savings calculator converts your current power company’s prices to an annual average inclusive price per unit (like ours) and then estimates how much you could save through Powershop per year.
We’re determined to save you money. By switching to Powershop most customers will save money, simply because they are not currently on the cheapest available tariff in their area now, and because Powershop aims to bring you some of New Zealand’s most competitive electricity deals. Use our savings calculator to estimate typical customer savings.
Powershop defines a customer as typical if they are on a common tariff, use between 4,000 – 15,000 kWh of electricity across the year in the relevant monthly profile shown below and who regularly purchase (either directly or automatically) the cheapest available Everyday product.
* This profile is the typical usage pattern of customers within each network area we supply and is based on historic data supplied by the Electricity Commission. You can also download this information in csv format.
Yes of course. If you're due a rebate from your lines company, they'll advise us of the correct amount and, depending on their instructions, we'll apply this to your Powershop account or pay it to you.
No it doesn’t, unless your property doesn't have an electricity supply and requires reconnection or connection to the electricity network (in which case special fees will apply and we will advise you of them before you incur them).
Powershop offers our customers on the Orion network who have a smart meter, a 5c/kWh monthly rebate on any power they consume between 7am -9pm, on Saturday and Sundays. We are able to do this because Orion (the local Christchurch network company) charges less for daytime line services over the weekends. All they needed was a retailer with systems smart enough to pass the savings on. A retailer like Powershop.
Powershop is currently available in Auckland, Franklin, Waikato, New Plymouth, Wanganui, Palmerston North, Horowhenua, Kapiti, Wairarapa towns, Wellington, Christchurch, Queenstown and Dunedin. We plan to extend our service across New Zealand. Click here to find out if we can supply your property.
We are adding new regions all the time. Sign up to keep me posted and we will let you know when we are available in your area.
This depends on the metering equipment installed in your premises. Currently we only support non ‘time-of-use’ meter configurations. However if you wish to switch but are unsure of your meter configuration you can call us on 0800 IN CONTROL (0800 462 668) and talk to us.
Yes, you can switch to Powershop if you have more than one meter.
No, unfortunately we can't supply prepaid meters at present. We may be able to in the future subscribe to our updates and we'll keep you posted.
Yes, you can switch to Powershop if you have a smart meter. If you are a smart meter customer we will enter into arrangements with the meter owner. Our preference is to try and get daily readings. This means your account balance will always be up to date.
Yes, you can switch to Powershop if you are moving to a new house. When you sign up online, select the option 'I'm planning to move to a new house soon (and want to set up Powershop for my new house)'. You can give us the details of the property you are moving to and your move in date as part of the signup process.
Yes, you can switch to Powershop if you have been disconnected or there is no current supply to your house. However, if you have been disconnected because you have not paid your current retailer they may not allow you to switch until you have paid them any outstanding bills, We will arrange for your power to be connected, but a reconnection fee will be charged - see our schedule of fees.
We do not currently supply gas, although this is something we are keen to do in the future. You can still switch to Powershop for electricity and remain with your current supplier for gas.
Yes, you can still switch to Powershop if you have your gas with another company. If you currently have dual gas and electricity supply from the same power company you can switch just your electricity supply over to Powershop and remain with your current power supplier for gas. You don't need to do anything differently when you fill in the application form to switch to Powershop.
No - Powershop supplies electricity to your home or business just like your current electricity supplier, so you won't need any special equipment or metering (the only exception to this is that if you have a prepay meter, you are not able to switch Powershop). You don't have to manage your account online if you don't want to but you will need a valid email address.
No, we don't require a bond, and the only time we'll charge you to join Powershop is when the property you're signing up doesn't have an electricity supply and requires us to organise reconnection or connection to the electricity network. Your old supplier may charge you for a final meter read in some circumstances - you'll need to check with them.
You can switch by signing up online, it only takes a few minutes and we'll do the rest, including contacting your old supplier - switch to Powershop now.
It will only to take a few minutes to sign up online and all you'll need is your preferred payment details (credit card or bank account). To help speed up the switching process you can give us your ICP number (you can find this on any of your current power bills) and a meter read.
Your property has a unique ICP number identifying it on the New Zealand electricity network. You can find your ICP number on your current power bill normally located under your invoice number. It consists of 15 digits – mostly numbers with a few letters at the end.
No, you don't need to talk to your old power company when you switch to Powershop, we'll do that for you. When we tell your current electricity supplier that you are switching to Powershop they are obliged to complete your switch within 28 days by giving us your final meter reading. They will use this final meter reading to send you the final bill for your account with them.
To ensure we can automatically top up your account if you forget or don't get around to buying power we need to set up a preferred default payment method either a credit, debit card or bank account details. This also means we don’t have to do credit checks or ask for bonds.
By entering your bank account details you are giving us permission to take money out of your account to pay for your power. In addition to ensure that we have the correct bank account details Powershop has a Direct Debit Confirmation Process that works in three steps:
No problem - you are covered by our 60 day guarantee.
After 60 days, if you’re not convinced Powershop is for you, we’ll help you reconnect to your old supplier and we’ll refund any unused electricity, no quibbles. Read our refund policy here.
If you decide to switch away after 60 days refunds will only be given in certain circumstances.
Call us toll free on 0800 462 668 between the hours or 9am - 9pm, Monday - Friday for assistance with switching.
No, your power won't be cut off (unless your current supplier has already threatened disconnection because you haven't paid them). Switching to Powershop just involves the transfer of information, we won't be touching any equipment affecting your supply.
We’ll be in frequent contact with you throughout the switching process (this could take anywhere up to a month to complete, but we’re able to switch most people in two weeks) and we'll let you know if you need to do anything.
Don't be surprised if you receive a phone call from your previous power company trying to convince you not to leave. Funny how they only seem to love you when you say you want to leave. You can be confident you have made a good choice to join Powershop. Feel free to call us on 0800 462 668 if you ever have any concerns.
Once you have been successfully switched over to Powershop we will let you know. You don’t have to do anything after your switch is completed, but we do recommend that you enter a meter reading some time in the first few days to bring your account balance up to date and to help us estimate how much power you are using each day.
No we don't send out paper bills. You can go online at anytime to view and print your account history.
No, but we will email you a monthly statement letting you know how much power you’ve used over the month and how much we will debit your account or credit card.
Your account will normally be reviewed monthly, usually after a meter read. After your account review we email you to let you know how much power you’ve used, and what the cost of any shortfall will be using your preferred product. You will have the opportunity to purchase power yourself by the day we notify you (a few days after the email), after this we will go ahead and buy as much of your preferred product as you need to cover your usage using your preferred payment method.
No, you don't have to buy you power in advance and you can treat Powershop just like you would any other power company. However if you do pay in advance through the online shop you could save more money by picking up special deals and purchasing in bulk.
You can pay for your power in arrears or in advance – it’s up to you. You can choose to pay for power yourself by buying products through the online shop, or you can leave it up to us and we will make purchases for you using your nominated preferred payment method.
Buying for power yourself:
If you want to buy power yourself just log in to the online shop and top up your account with whatever power product deals and specials that take your fancy. In this case we won’t need to send you any bills, but we will email you a receipt after each purchase.
Leaving it up to Powershop to buy your power:
If you want to leave it up to Powershop to buy power on your behalf you don’t need to do anything. Just keep using power as per normal and we’ll send you out a monthly email letting you know how much power you’ve used and how much we will debit your preferred payment method.
There are a number of ways to pay, these are -
By credit card - We accept Visa and Mastercard. You can set this up when you switch to Powershop, and the money will be debited from your credit card when you are billed or when you buy power yourself through the online shop.
By direct debit - You can set this up when you switch to Powershop, and the money will be debited from your bank account when you are billed or when you buy power yourself through the online shop.
By internet banking - You set this up through your bank's website. Choose the power you want from Powershop you then use your bank's bill payment process to make your payment.
By Pago - Ideal if you don’t have a credit card or don’t want to use bank account numbers on the internet. Sign up for Pago here.
By recharge card - You can top-up your account by cash or eftpos card with a Powershop recharge card at any PostShop nationwide. Read more about Recharge Cards.
No you won't be charged extra, there are no credit card transaction or convenience fees.
You don't need to worry if you can't access the internet to log in to the online shop and pay for your power. Powershop is not a prepay service so your power will not run out or be cut off if you don't have enough pre-purchased power. Just carry on as normal and either wait until you can access the internet so you can buy more power or wait until we send you out a bill after which we will automatically debit your bank account or credit card for the cost of the power that you have used.
You don't need to worry about going away and not being able to pay for your power. All customers that switch to Powershop are required to either set up a direct debit or credit card with us so we can automatically debit their account to cover any shortfall. If you are away when we review your account we will just make this debit, everything will carry on as normal. You just need to make sure there’s enough funds in there to cover your bill! Or if you prefer you can buy some power before you go on holiday.
With Powershop, you can top-up your account by cash or eftpos card at any PostShop using a Powershop recharge card. You can put money on to your Powershop account through your recharge card - you can do this to either pay your bill or to buy power in advance.
If you prefer to pay your bills with cash you can use a Powershop recharge card to pay at any NZ PostShop. To get a recharge card you need to either:
We aim to have the recharge card to you within three working days.
Powershop ran a signup promotion (that included a recharge card) with The Warehouse as part of our initial launch in February 2009. This promotion has now ended and recharge cards are no longer available in The Warehouse.
When you order a recharge card it will be associated with your account. Every time you go into a PostShop to pay for your Powershop bill or put money on to your Powershop account, you hand over your recharge card and the amount you pay will automatically get credited to your account. The minimum you can pay is amount is $25 and the maximum is $1000. Money is not stored on your recharge card, any recharge amounts are simply transferred to your Powershop account (this will normally occur within 15 minutes of payment).
Powershop is not a prepay service so it doesn't matter if you use more electricity that what you have paid for. Next time you top up your account you can cover this shortfall, or you can just wait for us to review your account and debit your preferred payment method.
You a free to login to the online shop and choose the kind of power you want to buy. There are a few different kinds and it's really up to you which kind you choose - there will be no difference to your actual power supply, but you will notice a difference in price, the time you can use the product, how much power use is covered by the product, and any other benefits associated with the product. If you decide you want to buy your power in advance you can choose how much you want to buy. Buy as much or as little as you like – all our power products have expiry dates so we will warn you if we think you are buying more power than what you can use. For more detail see How does the online shop work?
There are expiry or 'use-by' dates on the types of power products you purchase - this will only affect you if you choose to buy your power in advance. Typically the expiry dates are set to 2-3 months out, so as long as you don't buy more power than what you can use in this timeframe you won't need to worry about expiry. We will always warn you if we think you are buying too much.
Once power has expired it can no longer be used and cannot be refunded, just like a 'best-before date'. We do everything we can to reduce the risk of this happening.
We have expiry dates to give our suppliers more certainty and reduce their wholesale market price risk, helping Powershop customers access the cheapest prices possible.
If you pay for your power in advance you can get refund on any purchase, if you act within 48 hours of the time of that purchase. The money is refunded to your Powershop account (not your bank account or credit card) at the original purchase price. You can refund a purchase by going to the 'Account Statement' page under the 'My Account' tab. You'll find a Refund link next to all of your purchases that are eligible for a refund and you just click on that. For further details of our refund policy see our Refunds page.
We are the same as other retailers and we won't consider cutting your power off unless you have multiple outstanding payments, or repeatedly miss payments. It is important that you let us know if:
If this applies to you, let us know when you switch by filling out the section on ‘Vulnerability & Dependency’ when prompted during the signup process. You can also let us know when you are a customer at any time by logging into your account and selecting the ‘My Settings' section, then select ‘Vulnerability & Dependency', then select ‘yes' and provide details. Alternatively you can email us on admin@powershop.co.nz, or call us on 0800 IN CONTROL (0800 462 668), Monday to Friday, 9am to 9pm.
If you find yourself struggling to pay for your power, please let us know as soon as you can so we can avoid having to disconnect you. We can provide you with information on how to manage your electricity payments, or refer you to agencies that can help with budgeting advice and assistance. We also suggest you contact Work and Income by phoning 0800 559 009, as they may be able to provide you with financial assistance.

No, Powershop is not a prepay service and there is no requirement to 'stay in the green' in order to keep your power going. We will automatically top up your account each month using your preferred payment method if you have not bought enough power products to cover your usage, so you will not be cut-off if you don't login or you do not buy power during the month.
No electricity retailer can guarantee a continuous supply of electricity. If you, or anyone else at your property relies on a continuous supply of electricity for critical medical support and if you were cut off it may cause serious harm or loss of life you need to:
Regardless of which power company you might be with, your power is purchased from the New Zealand Electricity Market (NZEM) and comes from the national grid which transmits power from the various generators from around the country. There is no way of knowing (because it's physically impossible) which source of generation your electricity has come from. Read more about this in our blog Where does my power come from?
No. There is no possible way that Meridian-generated power can be given preferential treatment over any other power suppliers. The companies that offer you power through Powershop get their power from the national grid - this power could have been generated by any (or all) of the power generation companies in New Zealand.
Powershop operates a 24 hour 0800 faults service - 0800 IN CONTROL (0800 462 668). We will either arrange for the fault to be fixed or refer you on to the relevant party if the fault is outside of our control (e.g. the lines company).
In the event of any fault or problem with your power supply, power lines or meter you call us at our 24 hour 0800 faults service - 0800 IN CONTROL (0800 462 668).
We read customers' meters on a daily, monthly or bi-monthly basis depending on what area you live in.
For basic meters – meter readers will visit:
Auckland, Franklin, Horowhenua, Kapiti, Wellington, Christchurch, Queenstown, Dunedin (Monthly)
Waikato, New Plymouth, Palmerston North, Wanganui, Wairarapa (Bi-Monthly).
For smart meters – remote readings are taken:
ARC meters –
daily
AMS meters – monthly
If your meter is located inside your house we will need to arrange access.
No you don't have to read your meter yourself. We offer you the opportunity to enter your own meter reads online as often as you want so you can track your power usage, but regardless of whether you do this or not we will still read your meter every month (or bi-monthly).
Safety first ! Do not touch any part of your meter.
Common locations for your electricity meter are on a wall on the outside of your house, or inside perhaps in a porch or near the laundry. Meters will generally be located at the point where the power enters your property so look up to see if you can see where the power line comes in from the road.. In some apartment and multi-dwelling buildings, meters will grouped with other tenants’ meters – be sure to identify the correct meter (in some cases you will not be able to access these meters, this just means that your account balance will be estimated between our regular meter readings).
Safety first ! Do not touch any part of your meter.
It is easy! There are two common types of meter...
Digital meter: You read a digital meter from left to right – this means that the top reading in this example is 450, and the bottom reading is 1906. You can just ignore the red numbers.

Digital electricity meter example
Dial meter: If your dial meter has the 2 top dials in red, ignore them they are for testing purposes only – just read the bottom set of dials. When reading this type of meter, always take the number that the dial has just passed, even though this may not be the closest number to the dial. The reading for the dial meter shown in this example is 0794 (digits that are red or highlighted in red represent decimal places and can be ignored).

Dial electricity meter example
Be safe when you read your meter – if it's up high make sure that you reach it safely and if there are any loose or exposed wires in the cabinet don't touch them, but call an electrician as soon as possible.
No, but if you do you will be able to pick up cheaper power offers, special deals and you'll also start to learn more about your power usage.
The online shop has three main parts to it - your 'Unit Balance', the 'shop' and your 'account history'.
Unit Balance
Your 'Unit Balance' is the first screen you go to when log in. In this screen you can see what your meter readings are - these readings could have been updated by Powershop (after our meter readers have read you meter) or they could be estimates based on the last reading Powershop took and what we estimate your power usage has been since that time. You are free to update these readings yourself to keep things really accurate. Depending on how much power you have bought and used (or are estimated to have used) you will see how many units of power you have either in credit or are in arrears and you can see approximately how many days usage this equates to.
The Shop
If you decide you want to buy power go to the ‘Buy Power’ tab – this is where the ‘shop’ is and you can choose from a number of different power product deals and specials on offer. As you add power products to your cart you can see how many days the purchase will cover you for on the Power Organiser.
Account History
You can see your account history under the ‘My Account’ tab. There’s also great information that graphs your usage over time, how much you’ve spent on power products and what you have bought.
Power products are basically different blocks of power on offer through Powershop - our products can be for different amounts of power, for use at different times, help support your favourite team or causes, or come with additional benefits. There will be different reasons why you might want to buy different power products - you may want to buy the greenest products, the cheapest, one that supports a certain charity or one that is offered by a particular supplier. You are free to choose as many types of products as you like when you pay for your power.
There are a few Everyday products on offer in the shop – these products are the most flexible way to buy power. You can buy as much or as little Everyday power as you want and as often as you want. Everyday power is available for use as soon as you buy it.
A few products on offer through Powershop are ‘green’. Because the electricity that you use in your home or business comes from a mix of sources that you cannot control it’s impossible to use only ‘green’ generated power. What suppliers of green products on Powershop can do is offset the greenhouse gas emissions from electricity generated on your behalf by buying carbon credits effectively reducing your carbon footprint.
Specials are blocks of power that are usually cheaper or support a special cause. A Special will usually be about one week’s worth of power (depending on your power usage or the particular offer) and there may be restrictions on how many times you can purchase that particular Special, for example you may only be able to purchase it once, or only once a week. Specials are a great way to save money on power. It’s worth logging in to the shop frequently to see what’s on special.
Powerpacks are a great way to manage your budget because they allow you to buy power in bulk for the months ahead. From time-to-time there may also be special deals.
A Powerpack is usually power that is set aside for future use, so for example it may be that it can only be used during the winter months of June, July and August. It’s a great way of budgeting and smoothing out the cost of power over the year.
No you don’t have to buy power in advance if you use the online shop and you can treat Powershop just like you would any other power company. However if you do pay in advance through the online shop you could save more money by picking up special deals and purchasing in bulk.
If you've got any questions we are here with real people answering the phone on 0800 IN CONTROL (0800 462 668), Monday to Friday, 9am – 9pm.
We store your personal information on secure servers behind firewalls, so your details are safe and secure as long as you keep your password private. Powershop will not sell, lend, trade or otherwise disclose your personal information to any other person or agency except as set out in our privacy policy.
Yes, we use industry best practices to ensure that your credit card or bank account details are kept at the safest possible levels. For more details see our privacy policy.
Having more than one meter is generally beneficial - in basic terms it means that one meter is used during peak periods and the other one during off peak times when power is cheaper.
A tariff is a pricing structure (in the traditional power retailer sense), determined by the meter set up you have. There are many different names for the various tariffs across the industry. But they will normally indicate a time of use (e.g. Day and Night) or control (e.g. Uncontrolled, Anytime, Economy). Your pricing structure will remain the same if you switch to Powershop.
Controlled meters measure power use for appliances (usually hot water heating) which the local network company is able to switch off for short periods, for example when the demand on their network is high, or when faults or emergencies happen on their network. Usually there is a discounted rate given by the lines charges for allowing this, which is passed on to the customer. Uncontrolled metering simply means that the local network company has no way of ‘controlling’ or switching off appliances or use measured by that meter.
Day/ night metering involves two separate meters (or two registers on one meter), one of which measures ‘day’ usage, and one of which measures ‘night’ usage. This is usually beneficial as it allows retailers to measure (and charge lower rates for) your night usage.
Smart meters are a new generation of metering devices which are slowly being installed out by retailers across different regions in New Zealand. They differ from current ‘dumb’ meters by being able to measure consumption accurately across different time periods (e.g. days, nights and weekends) in the one meter. They also have two-way communication abilities to enable remote meter reading, and to enable instructions to be sent to the meter e.g. to remotely disconnect a property. There is currently considerable debate about what other functionality smart meters should have, see http://www.pce.parliament.nz and search for 'smart meters'.

The electrical energy consumed by a 1,000 watt (1 kilowatt) appliance in an hour is one kilowatt-hour (kWh). A ‘unit’ is the word we use for one kilowatt hour of power consumption. ‘Cents/ unit’ is the amount of cents each unit (or one kilowatt hour of consumption) will cost.
Your property has a unique ICP number identifying it on the New Zealand electricity network. You can find this on your current power bill somewhere under the invoice number. It consists of 15 digits – mostly numbers with a few letters at the end.
