We have introduced mandatory retailer reporting of domestic and small business customer data to help increase transparency and accountability in New Zealand’s retail electricity market. Retailers will need to submit data from 1 January to 31 July 2025 (inclusive) under the new retail market monitoring clause 2.16 notice on or before 31 August 2025 to the Authority. Following this, data will need to be submitted on a monthly basis.
