Air New Zealand has unveiled Hangar 4, a state-of-the-art aircraft maintenance facility that represents one of the airline’s most significant infrastructure investments. Part of the airline’s Auckland maintenance base in Māngere, Hangar 4 marks a bold step forward in operational capability and long-term growth strategy.

At 10,000 square metres, 35 metres high and 98 metres wide, Hangar 4’s scale allows Air New Zealand engineers to service a Boeing 787-9 Dreamliner and two Airbus A320/A321s simultaneously, supported by an additional 5000 square metres of specialist workshops and engineering spaces. Cutting a striking figure on the South Auckland skyline, the hangar has already become a landmark of note for arriving travellers.
Innovation and sustainability
Hangar 4, which is targeting a 6 Green Star Rating from the New Zealand Green Building Council, is the largest single-span timber arch aircraft hangar in the Southern hemisphere. Timber was chosen for its lighter weight, ability to be sourced sustainably – from plantations in Nelson and Wodonga – and for its performance in a coastal environment.
An ETFE roof delivers natural light and retains heat without the need for a heating system, aided by ceiling fans that circulate warm air in winter and providing cooling in summer. Prefabricated trusses, each weighing 38 tonnes, were built in 25-metre sections, assembled on site and lifted into place using New Zealand’s largest crawler crane – a unique construction method at this scale.
Underground service pits eliminate the need for surface cabling, offering both flexibility and efficiency for maintenance teams. The structure also connects with the adjacent Hangar 3 via shared workshops and tool stores, boosting efficiency across maintenance programmes.
