Information disclosure

Under subpart 11 of Part 4 of the Commerce Act 1986, suppliers of specified airport services are subject to information disclosure regulation.

Specified airport services have the meaning given to them in section 56A of the Act. The specified suppliers are the companies operating Auckland, Christchurch and Wellington International Airports.

The Commission's determination may require suppliers to disclose certain specified information relevant to their performance (such as financial statements, prices and quality performance measures), including forward-looking information (such as forecasts and asset management plans).

The purpose of this form of regulation is to ensure that sufficient information is readily available to interested persons to assess whether the purpose of Part 4 is being met.

Information on the approach to information disclosure regulation can be found in the archive.

Input methodologies review

The Commission reviewed how regulated airports’ profitability is assessed under information disclosure regulation and, in particular, whether changes to information disclosure requirements and IMs can support this assessment.

We published our decisions papers in December 2016. All papers and supporting documents, including amendments to the IM Determinations can now be found on the IM review webpage.
