Improving retail market monitoring

We want to improve how we monitor the retail market to improve outcomes for all consumers.

    • Overview

    On 17 March 2025, we published our decision to bring the new Retail Market Monitoring clause 2016 information notice into effect to increase transparency and accountability in New Zealand’s retail electricity market. This replaces the Retailer Financial Stress notice under clause 2.16 that took effect from 1 October 2022 to 14 August 2025.

    Retailers submitted their first set of data by 31 August 2025, and this reporting will continue every month. We have started processing the data and will share updates as we analyse and publish insights.

    Technical and non-controversial changes

    We have made the following technical and non-controversial changes to the ‘Retail market monitoring clause 2.16 information notice’ in response to feedback:

    • changed T4.11 Time of Day from a mandatory to a non-mandatory field
    • updated the naming convention so that participant codes are not included in the file names
    • added an option to split large tables into two or more files
    • changed Table 5’s reference in T5.4 from ‘Integer’ to ‘Numeric’
    • removed spaces from the file names in Appendix A.

    Frequently asked questions

    We are updating our frequently asked questions every fortnight to support retailers to implement this requirement and welcome any questions to retaildata@ea.govt.nz

    Extensions

    We have approved two extensions for exceptional circumstances to the 31 August 2025 deadline: For Our Good Limited and Hanergy Limited.

    Project background

    As a modern regulator, we develop insights based on accurate data. Improving our collecting and monitoring of retail data will enable us to have better visibility of the retail market. This increased visibility will enable us to identify potential issues, publish more insights and make well-informed policy decisions that will benefit consumers.
