Most Satisfied Customers | Powershop

Powershop has edged out last year’s winner to reclaim the top spot as New Zealand’s highest-rated power company. Powershop scored five stars across most research categories in 2018, leading the way from 11 other electricity providers on customer satisfaction.

Finding the best power company for your home

Are you anxious about your next electricity bill? You’re not alone. In fact, more than a third of the respondents (36%) that we surveyed said they worry about their power bills. Most New Zealanders seem to be rather energy-savvy, with 68% using energy saving lightbulbs, 58% saying their home is well-insulated, and slightly more than half (51%) remembering not to leave appliances on standby mode. While reducing your electricity consumption will naturally save you on energy bills, you may still be paying too much for electricity if you haven’t compared retailers to find the best price. Our research found that a disappointingly low 38% of respondents have compared electricity prices in the last 12 months, while only 14% of customers have switched.

If you haven’t compared power companies for some time, you may be paying too much for power. Or maybe you’re just not getting the level of service you deserve? The good news is we are spoiled for choice when it comes to electricity retailers in New Zealand, with more than 30 companies competing for our business. But with all the competition brings confusion – how are you supposed to know which power company will offer the best service and price?

That’s why Canstar Blue annually surveys thousands of electricity customers across NZ to help you make a more-informed decision. You’ll never really know how good, or bad, an energy company will be until you’ve signed up, so we think our ratings provide a very helpful guide because they are based on the real-world experiences of consumers just like you.

In this year’s ratings, Powershop has taken back its throne as New Zealand’s highest-rated power company, with customers rating it five stars across most research areas, including customer service. Powershop also produced strong four-star results in value for money and bill and cost clarity.

It means Powershop has topped our ratings in six out of the last seven years.

  • Another commendable performer was last year’s winner, Electric Kiwi. While the retailer couldn’t make it two-in-a-row, it did manage five stars on value for money, bill & cost clarity and tools and advice.
  • Energy Online, Flick Electric Co, Mercury Energy, Meridian Energy, Nova Energy and Pulse Energy all scored four stars for overall customer satisfaction.
  • Contact Energy, Globug, Genesis Energy and Trustpower all received three stars for overall customer satisfaction.

So with so many power companies to choose from, how do you find the right one for you? Canstar Blue has put together a guide to help you navigate the market and find the best deal to suit your preferences and needs.

Understanding your power bill

Your power bill has two components – fixed charges and variable charges. It will also include any additional fees, discounts, rebates and taxes that may apply.

Daily fixed charge: This is a fixed charge of anywhere from 30 cents to $2 per day for standard users. This covers the cost of metering and network maintenance, and applies regardless of whether or not you use any electricity that day.

Variable rate charge: This is a charge for the electricity you actually use, measured in kilowatt hours (kWh). There are different types of variable rate charges to pick from, depending on the type of meter you have.

  • Anytime: The same variable rate is charged on electricity usage at all times
  • Time-of-use (TOU): Different rates apply at different times of day. Electricity is most expensive during the peak demand times and cheapest during low-demand periods. The times and rates vary across distribution networks, with TOU only available to households with smart meters. Some retailers also provide ‘spot pricing tariffs‘ whereby prices reflect the wholesale cost of energy at half-hour intervals.
  • Controlled: Appliances fixed to a separate meter circuit are charged a lower rate on electricity, but are only supplied during off-peak hours. This can be used in conjunction with a day/night, anytime or TOU agreement
  • Day/Night: Similar to a time-of use agreement, a high variable rate applies between 7am and 11pm (day), while a low variable rate applies between 11pm and 7am (night)
  • Night only: Nominated appliances are only supplied electricity for eight hours per day between the hours of 11pm and 7am. While supply availability is limited, a lower rate applies. Some retailers offer ‘Night booster’ if you need a few more hours of supply.

Spot Pricing

Spot pricing is a relatively new tariff that is growing increasingly common. To understand spot pricing tariffs, you first need a basic idea of how the market operates. Essentially, generators sell electricity on a wholesale market which is then bought by electricity retailers. The price that the retailer pays on the wholesale market is called the “spot price” which will change every 30 minutes. Most retailers charge a flat rate for electricity which retailers calculate by averaging the expected spot price over the next year. Retailers will usually add a little on top of this rate to cover their own operating costs and profits.

Customers on a spot pricing tariff, however, will only pay the wholesale price for electricity and retailers will cover their own costs through a daily fixed fee. This means that electricity retailers don’t profit from the amount of electricity you use. Spot prices can be incredibly volatile, so make sure you know what you’re getting into before signing up.

Standard User vs Low User Plans

There are two types of electricity contracts in NZ – Standard User and Low User. Some power companies may refer to these contract types by different names, but they are all principally the same.

  • Low User Plan: Customers will receive a high variable rate on electricity usage – around 25 to 40 cents per kWh, and a low daily fixed charge – usually no more than about 30 cents a day. Households in the lower half of South Island are considered Low Users if they consume 9,000kWh of electricity per annum, but a lower threshold of 8,000kWh per year applies elsewhere in New Zealand (pictured)
  • Standard plan: This is the most common type of energy contract. It has a high daily charge, but low variable charge of around 20 to 30 cents per kWh depending on its type

Electricity Discounts

Power companies like to reward customers who make their life easier with discounts, which can be a great way to reduce your overall costs. There are four types of discount you’re likely to encounter with NZ power companies:

  • Prompt payment discount: This is a discount of around 10% to 20% for customers who pay their power bills in full and on time.
  • Direct debit: While less common, some NZ retailers offer a small discount of a few percent to customers who pay their bill via direct debit.
  • Email correspondence: A small discount of about 1% to 2% may be offered to customers who receive their bills and correspondence via email.
  • Dual fuel discount: Energy providers who supply both electricity and gas sometimes provide a bonus discount to customers who have dual accounts with them.

NZ Power Companies Compared

A power company must have received at least 30 responses from survey respondents to score itself a spot in our 2018 customer satisfaction ratings. This year, there were 12 power companies able to meet this threshold. Here’s what these companies have on offer:


powershop logo

Powershop is a unique power company in the NZ market, offering what it calls “Powerpacks” – pre-purchased energy deals that Powershop customers can buy to receive lower rates or better discounts. This gives customers the power to pay in advance, pay as you go, or simply pay the old-fashioned way when you receive your bill. Powershop also gives its customers access to useful online tools and mobile apps that let them monitor and control their energy usage. Powershop is so confident in its product that it guarantees customers will save at least $150 in the first year after switching. Powershop will monitor what you would have paid with your old retailer, and if you haven’t saved at least $150, Powershop will credit you the difference.

Key takeouts:

  • $150 guaranteed saving in first year
  • Winner of Canstar Blue’s electricity provider award: 2011-16, 2018
  • Powerpacks give customers flexibility in how they pay for energy

Electric Kiwi

Electric Kiwi claims to be an affordable and flexible electricity retailer, offering no lock-in contracts and what it claims are “everyday low prices”. Electric Kiwi also guarantees that customers will save in their first year after switching. Electric Kiwi will monitor what new customers will have paid for power with their old retailer and if they haven’t saved, they will be credited the difference. One of the most exciting features of Electric Kiwi however, is its “hour of power”. Electric Kiwi customers nominate one hour per day during off peak period (9am-5pm & 9pm-7am) to receive free electricity – yes, 100% free electricity. Customers can use this time to run their dishwasher, washing machine, clothes dryer, car chargers or other high-use appliances to save on power.

Key takeouts:

  • Low rates and flexible contracts
  • Guaranteed savings in the first year
  • One hour per day of free electricity

Energy Online

Energy Online boasts the slogan “brilliantly simple”, promoting itself as an affordable and easy to understand electricity company. Energy Online provides electricity, natural gas and bottled LPG and a 20% prompt payment discount for customers who pay their bill on time and in full. There are no fixed-term contracts or exit fees, so you’re free to leave at any time and the price plan you join on is guaranteed for 12 months.

Key takeouts:

  • 12mth Price Plan Promise
  • 20% prompt payment discount
  • No exit fees
  • Dual-fuel offering

Flick Electric

Flick Electric claims it is “totally different” to the other power companies. While most retailers charge a fixed price for electricity, which is adjusted to incorporate its profit margins, Flick Electric only passes through the wholesale price of electricity. That means Flick Energy doesn’t benefit from its customers using more power, so it has genuine incentive to help them save. Flick Energy instead makes its revenue by charging a daily fixed “retailer charge”. Flick Electric also says it endeavours to be transparent, with live price alerts on spot prices and weekly billing to keep bills manageable.

Key takeouts:

  • Only pay wholesale price for electricity
  • Mobile app and price alerts
  • Weekly billing

Pulse Energy


Pulse Energy is a New Zealand community-owned energy company, supplying electricity, gas and solar to more than 70,000 households throughout the country. Pulse Energy says it could beat the electricity rates you are currently on with its ‘Price Promise’ but terms and conditions apply. It also says it offers customers a low price upfront, ‘Price Protection’ on their energy rate for two years (again conditions apply), and no long-term contracts.

Key takeouts:

  • Price promise offer
  • Price protection on energy rates for 2 years
  • No long-term contracts

Meridian Energy

Meridian Energy is one of the largest renewable generators in the Oceania region. Its attitude towards sustainability is reflected in its retail services, with all its electricity being sourced from wind and water whenever possible. Meridian Energy recently replaced prompt payment discounts as it considers them fundamentally unfair. The company now offers a new lower rate for a simpler and fairer approach for everyone, it says. There are regular and changing offers for new customers.

Key takeouts:

  • Environmentally-friendly retailer
  • Options for welcome credit or Crusaders jersey

Nova Energy

The Home Freedom Plan is simple, with variable pricing and no fixed contract term or early termination fees. The Home Advantage Plan gives customers $100 signup credit and fixes the rates you pay on electricity until 2020 – protecting you from the cost of rising power prices.

Key takeouts:

Key takeouts:

  • One of New Zealand’s largest energy companies
  • Three options with varying contract periods
  • Can earn flybuys points for paying your bill



Globug lets customers pay their power bills as they go, which it says makes it much easier to manage your electricity spending. The Globug app lets you monitor your electricity usage and pay towards your account whenever you feel like. There are no penalties or payment fees, so you have complete control over your power spending. While Globug will send you alerts when your balance is low, customers must be proactive in keeping on top of their energy account.

Key takeouts:

  • Pay as you go energy
  • Handy phone app that lets you control and track usage

Contact Energy

Contact Energy is an integrated electricity retailer and generator, as well as a home internet supplier. It has three electricity products on offer: Saver Plus, Freedom and Fuel Rewards Plus.

What is the cheapest power company in New Zealand?

The cheapest power company for your home will depend on your location, tariff type and energy consumption habits. Despite what some retailers may claim, there is simply not one energy company that will be the cheapest in every case. When considering electricity prices in NZ, it’s important to look past the headline discounts and sign-up incentives, and carefully assess the rates and any terms such as added fees. Keep in mind this checklist:

  • The type of contract – standard or low user
  • How much you pay in variable and daily fixed charges
  • Whether your variable rate will change
  • What percentage discount you receive on your bill
  • Whether you have a single rate or time of use tariff
  • Whether you have a controlled load for water heating

Also, don’t overlook the little guys. While the larger power companies can claim their market power allows them to offer the best value, many smaller power companies have produced some innovative approaches to energy that may help your dollar go further. P2, for example, is New Zealand’s only peer to peer solar trade platform, while Giving Energy lets customers donate to organisations simply by paying their bills.

Electricity Distributors in New Zealand

Energy distributors are responsible for maintaining the infrastructure that transports electricity from the generators to your home. There are dozens of distribution companies that combine to form the energy grid. These are:

  • Top Energy
  • NorthPower
  • Vector
  • Counties Power
  • WEL Networks
  • Waipa Networks
  • Powerco
  • The Lines Company
  • Horizon Energy
  • Eastland Network
  • Unison Networks
  • Centralines
  • Scanpower
  • Electra
  • Wellington electricity
  • Nelson Electricity
  • Network Tasman
  • Marlborough Lines
  • Mainpower
  • Buller Electricity
  • Westpower
  • Orion
  • Electricity Ashburton
  • Alpine Energy
  • Network Waitaki
  • Aurora Energy
  • OtagoNet
  • Aurora Energy
  • The Power Company
  • Electricity Invercargill

A large proportion of the rates that you’re charged for electricity are attributed to distributor costs, meaning the price you pay will vary across different distribution networks. Perhaps factor in potential price of energy if you’re considering moving to an area that straddles multiple networks.

Frequently asked questions

Canstar Blue commissioned I-view to survey 5,000 New Zealand consumers across a range of categories to measure and track customer satisfaction. The outcomes reported are the results from customers who have an electricity account in their name and pay the bills – in this case, 4,251 New Zealanders.
Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then alphabetically. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criteria.
