Wellington International Airport (Māori: Taunga Rererangi o Te Whanganui-a-Tara; formerly known as Rongotai Airport) (IATA: WLG, ICAO: NZWN) is an international airport located in the suburb of Rongotai in Wellington. It lies 3 NM or 5.5 km south-east from the city centre. It is a hub for Air New Zealand and Sounds Air. Wellington International Airport Limited, a joint venture between Infratil and the Wellington City Council, operates the airport. Wellington is the third busiest airport in New Zealand after Auckland and Christchurch, handling a total of 3,455,858 passengers in the year ending June 2022, and the third busiest in terms of aircraft movements. The airport, in addition to linking many New Zealand destinations with national and regional carriers, also has links to major cities in eastern Australia. It is the home of some smaller general aviation businesses, including the Wellington Aero Club, which operates from the general aviation area on the western side of the runway.

The airport comprises a small 110-hectare (270-acre) site on the Rongotai isthmus, a stretch of low-lying land between Wellington proper and the Miramar Peninsula. It operates a single 2,081-metre (6,827 ft) runway with ILS in both directions. The airport handles turboprop, narrow-body and wide-body jet aircraft movements.
