What we do
Our role is to regulate the New Zealand electricity market.
We develop, administer and enforce the market rules that govern nearly every aspect of New Zealand’s electricity industry including generation, transmission, system operation, security of supply, market arrangements, metering, distribution and retail.
We contract service providers to operate the electricity market and system.
We analyse and monitor the performance of the market and the electricity industry and make the information available on our EMI website - short for Electricity Market Information.
The EMI website has a wide range of information, including data on retailer market share, monthly switching reports and wholesale final pricing.
We help develop the industry through education, guidelines, information and model arrangements.
Our day-to-day work focuses on addressing key questions that affect the long-term benefit of electricity consumers.
Purpose – statutory objective
Our statutory objective is to promote competition in, reliable supply by, and the efficient operation of, the electricity industry for the long-term benefit of consumers.
