2017 award for electricity providers

Most Satisfied Customers | Electric Kiwi

After dominating the ratings for several years, Powershop has finally been replaced at the top of the standings. The new kid on the block is Electric Kiwi, achieving five-star reviews in most categories, including overall customer satisfaction.

Which power company is best for you?

Electricity tends to be something we take for granted, that is, until the bill arrives. More than one-third (36%) of the New Zealanders Canstar Blue surveyed said they worry about the cost of their power bill, yet many of us aren’t taking any action. Fewer than half (41%) of the respondents we spoke to claimed to have compared power companies in the last 12 months, while only 13% made the switch. However, putting in the effort to compare companies and potentially switch could easily pay off.

The NZ electricity market is extremely competitive, with more than 30 power suppliers for customers to choose from. Unfortunately, many of us aren’t taking advantage of this, meaning households are paying more for power than they need to – something Canstar Blue hopes to help with in this 2017 review.

Each year, Canstar Blue asks thousands of electricity customers to rate their provider on key criteria, including customer service, bill and cost clarity, value for money and overall satisfaction. This year 12 different power companies received a sufficient response to feature in our results.

Electric Kiwi has taken the top spot in this year’s ratings, receiving a maximum five stars in all but one area. This is a particularly impressive feat in light of the fact that this category has been dominated by Powershop for the past five years running. With a new winner crowned and three brands in hot-pursuit scoring four-stars for overall satisfaction, it seems that power companies have really stepped up their game of late.

While this is all great news for the customer, this increasing closeness of competition means we have to be more vigilant about regularly shopping around to find the best deal on energy. To get you started, this report will work you through the basics of navigating the New Zealand electricity market and then provide some details about the power companies operating in NZ to help you find a better deal.

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.

Daily fixed charge: This is a fixed charge 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 choose 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 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
  • 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 only: Nominated appliances are only supplied electricity for eight hours per day between the hours of 11pm and 7am. Similar to a controlled setup, while supply availability is limited, a lower rate applies. Some retailers offer ‘Night booster’ if you needafew more hours of supply.

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 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

Electricity retailers 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

Although Powershop gives you the option to pay for power in the more traditional way, it also gives you the opportunity to pre-purchase electricity in advance at lower rates.

This can help you take advantage of promotional offers and, in some cases, make it easier to budget.

Who 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 claim, there is simply not one energy company that will be the cheapest in every case. When considering electricity prices, 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 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 portion of the rates 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.

How to get the best deal on electricity

Anyone can find a great deal on energy, so long as they’ve educated themselves about their options and done some research. New Zealanders have plenty of power companies to choose from, so it’s important to regularly canvass the market to see if you can find a better price. Canstar Blue’s customer satisfaction ratings give a direct insight into what other energy customers think about a particular brand, making it a great place to start comparing. Good luck!

Frequently asked questions

Canstar Blue commissioned I-view to survey 2,500 New Zealand consumers across a range of categories to measure and track customer satisfaction. The outcomes reported are the results from customers within the survey group who currently have an electricity account and pay the bills – in this case, 2,108 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.
