Auckland Airport (IATA: AKL, ICAO: NZAA) is an international airport serving Auckland, the most populous city of New Zealand. It is the largest and busiest airport in the country, with over 18.7 million passengers served in the year ended December 2024. The airport is located near Māngere, a residential suburb, and Airport Oaks, a service-hub suburb 21 kilometres (13 mi) south of the Auckland city centre. It serves as the principal hub for Air New Zealand, and the New Zealand operating base for Jetstar.

The airport is one of New Zealand's most important infrastructure assets, providing several thousand jobs for the region. It handled 71 per cent of the country's international air passenger arrivals and departures in 2000. It is one of only two commercial airports in New Zealand that can handle Airbus A380 jet aircraft (the other being Christchurch).

The airport has a single 3,635 m (11,926 ft) runway, 05R/23L, which is Cat IIIb capable (at a reduced rate of movements) in the 23L direction. It has a capacity of about 45 flight movements per hour, and is currently the busiest single-runway airport in Oceania. In November 2007 work began on a new northern runway, to be built in several stages and to be used mainly by smaller aircraft, freeing up capacity on the main runway.
