We are setting DPP4 in the context of an energy transition to increased electrification, climate change impacts, high inflation, and significant cost pressures facing both EDBs and consumers.

Current step in the process

On 29 May 2024 we published our draft decision and Commissioner Vhari McWha hosted a presentation to stakeholders and media and Q&A session. Details on the draft decision reasons paper, models, determination can be found at the end of this page.

Submissions close 5pm, Friday 12 July 2024, and cross-submissions close 5pm, Friday 2 August 2024. Submissions should be addressed to: Ben Woodham, Electricity Distribution Manager c/o infrastructure.regulation@comcom.govt.nz - please include ‘Submission on EDB DPP4 draft decision’ in the subject line of your email. Please note that no extensions will be granted to these consultation deadlines due to the statutory requirement for us to publish our final decisions by 30 November 2024.

We have also published a webpage explaining more about the estimated impact of these decisions on consumer electricity bills. You can read more about this on our website.
