Changes to information disclosure requirements for airports 2026
We are working on improvements to information disclosed by airports.
In 2025, we completed the latest round of reviews of price-setting events (PSEs) by three regulated airports. After we finished the review of Auckland Airport’s price-setting event 4 (PSE4), the Ministry of Business, Innovation and Employment (MBIE) carried out targeted consultation with airport stakeholders on the regulation of airport servicesopen_in_new. It found that the Commission could potentially improve information disclosure (ID) regulation during times of major capital investment.
We subsequently received a letter from Air New Zealand, requesting that the Commission undertake an inquiry, under section 56G of the Commerce Act 1986 (the Act), into airport regulation.
On 6 October 2025, we responded to that request and published a report titled “Targeted Assessment of Airport Regulation”, which looked at ways we could improve airport regulation, particularly on airports’ major capital expenditure decisions. We decided not to initiate a section 56G inquiry at that time. However, we considered additional ID requirements relating to major capex decision processes could be beneficial. It is in this context that we have taken the next step and initiated this project.
