Five alleged breaches of Code being investigated

The Electricity Authority Te Mana Hiko has started five investigations into alleged breaches of the Electricity Industry Participation Code.

There are three investigations into Genesis Energy, one into Nova Energy and one into Waverley Wind Farm Limited.

The Nova Energy investigation is related to the alleged disconnection of a medically dependent consumer. This is a potential breach under our Consumer Care Obligations.

Two investigations (one for Genesis and the one for Waverley) are about an alleged failure to comply with intermittent generation dispatch, and the other two for Genesis relate to inaccurate unmetered load databases resulting in inaccurate reconciliation submissions.

Here are the investigation notices:

• Genesis - alleged dispatch non-compliance at Waipipi wind farm
• Genesis - alleged breaches of DUML database accuracy and submission info
• Genesis - alleged breaches of DUML database accuracy and submission info
• Nova Energy - alleged disconnection of known medically dependent consumer premises
• Waverley Wind Farm Limited - alleged dispatch non-compliance at Waipipi wind farm

Any participant who believes they are affected by the matter under investigation and wishes to become a party to the investigation, should notify the investigator by 5pm, 23 December 2025. The investigator can be contacted, citing the reference number, by email to compliance@ea.govt.nz

The Authority is responsible for investigating and enforcing compliance with the Code. Compliance is one of our core functions and a strong focus. A secure, resilient, and efficient electricity system depends on all participants complying with their obligations under the Code.

Our approach to compliance is set out in our compliance strategy, framework and related policies on our website. These outline how we monitor, investigate and enforce compliance, and the principles that guide our work - transparency, proportionality, and fairness. The framework covers everything from compliance monitoring priorities and education to formal investigations and enforcement actions.
