We regulate New Zealand’s electricity market.
Electricity is created when electrons flow through a conducting material, such as the copper or aluminium used in power lines.
Electricity meters keep track of how much power you are using. There are either analogue or smart meters.
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.
New Zealand has one of the fastest switching times in the world.
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.
We have made it easy for you to access information about your power.
Your bill shows how much power you have used and how much you need to pay.
Our market development work is important to achieving our statutory objective to promote competition in, reliable supply by and the efficient operation of the electricity industry for the long-term benefit of consumers.
A number of different groups provide us with specialist independent and technical advice and recommendations.

Participants in the electricity industry must register with us and be listed on the industry participant register.
We contract a range of market operation service providers to operate the electricity markets.
The Electricity Industry Act 2010 allows us to amend the Code and sets out the process we must follow.
The Code sets out industry participant responsibilities, including our own duties and responsibilities.
