Airports

Input methodologies for specified airport services supplied by the companies operating Auckland, Christchurch and Wellington International Airports were determined in December 2010.

These suppliers  are subject to the regulatory provisions under subpart 11 of Part 4 of the Commerce Act 1986 (the Act). Specified airport services are defined in section 55A of the Act and relate to aircraft and freight activities, airfield activities and specified passenger terminal activities. Airport companies are subject to information disclosure regulation only.

The Commission made its input methodologies determination for airport services on 22 December 2010 and published the determination in the New Zealand Gazette on 20 January 2011.  The determination includes input methodologies for asset valuation, cost allocation, regulatory tax treatment and the cost of capital.    

The Commission must review each input methodology no later than 7 years after its date of publication and, after that, at intervals of no more than 7 years.
