The purpose of Part 3 is to promote competition in the electricity industry:

  • by prohibiting a person who is involved in a distributor from being involved in a generator where that may create incentives and opportunities to inhibit competition in the electricity industry; and
  • by restricting relationships between a distributor and a generator or a retailer, where those relationships may not otherwise be at arm's-length.

Prior to 1 November 2010, this function was the responsibility of the Commerce Commission under the Electricity Industry Reform Act 1998 (EIR Act). A list of the decisions made by the Commerce Commission on applications for exemption can be found in the exemptions register.

All exemptions received after 1 November 2010 can be found on the Authority's register.

Further information on Part 3 can be found under the headings for sections 77, 88, 89 and 90 below, or in the Guidelines on Part 3 of the Electricity Industry Act 2010 below, or by sending an email to our market operations team with 'Part 3 enquiries' in the title.
