We monitor the electricity industry for competitiveness, efficiency and reliability to see if any improvements can be made for the long-term benefit of consumers.
Our electricity market information (EMI) website has a wide range of performance metrics, analytical tools and data available to view or download, for example, retailer market share, monthly switching reports, wholesale final pricing and much more.
If an anomalous event or outcome occurs in the market or the broader electricity sector, we investigate it to determine the causes and whether something can or should be done to prevent such an event or outcome from occurring again.
You can interact with the icons and visualisations to explore the data and find out more about New Zealand's electricity market.
