What does the Electricity Authority do?

We regulate New Zealand’s electricity market.

What is electricity?

Electricity is created when electrons flow through a conducting material, such as the copper or aluminium used in power lines.

How does electricity get to my house?

What are smart meters?

Electricity meters keep track of how much power you are using. There are either analogue or smart meters.

  • Does my meter need to be recertified?

What are my rights as an electricity consumer?

You need to sign a contract with the electricity retailer you've chosen. This contract protects you and your rights. It’s important to read and understand the terms and conditions.

  • What are my rights around disconnections?
  • What happens if the hydro lakes are low?

  • What happens if my retailer goes out of business?
  • Will switching affect the reliability of my electricity?

How do I generate my own electricity?

Innovations in the electricity sector are providing new ways to generate, store and even sell electricity through technology such as solar panels, small wind turbines, and batteries.

    It is important that new entrant retailers have a ‘level playing field’ for competing for customers, and that saves and win-backs do not impede efficient competition. This project considers whether to amend the Electricity Industry Participation Code 2010 (Code) in response to the post-implementation review of the 'saves' Code provisions.
