Setting and enforcing the Code

We set the Electricity Industry Participation Code 2010 - it's the rules that governs nearly every aspect of New Zealand's electricity industry.

It's each industry participant’s responsibility to comply with industry regulations and the Code, but we're here to support and advise.

We monitor and enforce the rules so that participants operate on a level playing field and consumers are treated fairly.
