The purpose of Part 4 of the Commerce Act 1986 is to promote the long-term benefits for consumers in markets where there is little or no competition and little or no likelihood of a substantial increase in competition.

Part 4 requires GDBs and the GTB to disclose information about their performance with the aim of encouraging them to improve efficiency and quality as well as incentives to innovate and invest.

The legal framework we apply when setting or amending ID requirements is set out in the Part 4 Information Disclosure Framework paper.
