Non-discrimination obligations monitoring and compliance documents

The Electricity Authority Te Mana Hiko has published three documents that set out how it intends to monitor compliance with the non-discrimination obligations (NDOs) requirements, including the retail price consistency assessment (RPCA), that come into force on 1 July 2026.

The NDOs seek to ensure the even-handed supply of risk management contracts to give confidence to independent generators and retailers that they can compete on a level playing field with gentailers. This is to promote competition in the electricity industry for the long-term benefit of consumers.

The three documents we have published are:

• Monitoring approach: Non-discrimination obligations and Retail Price Consistency Assessment
  This document describes how the Authority will monitor and enforce the NDOs, including the RPCA, requirements that apply to the four major gentailers. It covers how we will approach the monitoring and what documents and data will be used.

• ​​Retail Price Consistency Assessment information form
  The retail price consistency assessment report must be in the form specified by the Authority (clause 13.236W(6)). This form applies to gentailers and specifies how information must be provided to meet RPCA requirements.

• Retail gross margin and gentailer cost information form
  This information must be in the form and manner specified by the Authority (clause 13.259(4) and 13.259A(3)). Retailers with at least 1% of ICPs over the 12 months preceding the end of their financial year are required to provide retail gross margin information to the Authority related to the sale of electricity to mass market customers. Gentailers must only provide cost information relating to the sale of electricity to mass market customers over their last financial year.

The information forms are to help ensure the right data is submitted to the Authority for monitoring at the right time and in the right format. Issues identified by the monitoring process that warrant further inquiry may be considered under the Authority’s usual compliance and enforcement processes.
