Our electricity that powers more than 230,000 homes across the country comes from many hydro stations throughout New Zealand’s North and South Islands. We hope this dedication to renewable energy helps keep our country beautiful for generations to come, and is in line with the government’s long-term Energy Strategy. This strategy aims for 90% of New Zealand’s electricity supply to come from renewable sources by 2025.

Your power questions, answered

How do I choose an electricity company?

Smart kiwis on the hunt to find reliable, cheap electricity are willing to shop around for the best options. You’ll want to find a company that fits your values - perhaps sustainability is one of these - and that will offer home energy plans to fit in with your unique lifestyle.

How do I compare energy prices?

Energy rates are commonly measured in cents per kilowatt hour (KWH). These can vary seasonally, making it difficult to directly compare electricity prices. To get the best deal, we recommend you first ascertain whether you are a standard or low user, using the usage calculator included in the plan builder process. Then, you can get estimated daily charges to help you compare home energy prices.

What is the average New Zealand power bill?

According to the Ministry of Business, Innovation and employment, the average New Zealand household spent $2,101 on power in 2015. This equates to an average monthly power bill of $166.75, per household. However, consumption changes drastically season to season and is extremely dependent on dwelling size and location.
