We have decided to progress with the proposed Code amendment, with some changes in response to submitter feedback and input from the Common Quality Technical Group. The Code amendment will require asset owners to provide common quality-related information to the System Operator that meets the technical specifications set out in a new system operation document.

The Code amendments come into effect on 1 July 2026.

The Authority is inviting comments on its proposal to incorporate the approved CACTIS by reference into the Code, as required under Schedule 2 of the Legislation Act. We ask that any comments are provided no later than 14 April 2026.

Consultation

Thanks to all who provided feedback. We are considering all submissions and expect to share our decision in April 2026.

This consultation sought feedback on a Code amendment proposal that would ensure the System Operator has timely access to accurate information about assets connected to the power system.

We propose to amend the Code to:

  • update and clarify the common quality-related information requirements in the Code, and
  • incorporate a new system operation document containing technical specifications for the common quality-related information requirements.

The proposal follows on from our consultation Addressing common quality information requirements.

The options will be implemented in a staged approach, allowing us to first address immediate concerns. We will then turn our attention to developing solutions to enable the sharing of common quality-related information between the system operator and Transpower, as a transmission network owner, and with distributors.
