New Air New Zealand Hangar With Timber Roof Nears Completion

Air New Zealand’s Hangar 4 has reached a major milestone with the installation of its 27-meter-high (88.5 feet), 80-meter-wide (262 feet) hangar door, Wood Central reported (8-18-25). Engineered by Finnish manufacturer Champion Door Oy and installed by PENSA DOORS NZ, the door marks the final step before the carrier moves into what will be the world’s largest single-span timber hangar.

The new facility in Auckland is large enough to accommodate the airline’s fleet, including a Boeing 777, a Dreamliner 787, or two A320/21 jets side by side. Constructed from engineered wood, the hangar is designed for sustainability, structural strength, and seismic resilience.

Designed by Studio Pacific Architecture, the hangar incorporates more than 1,200 m³ of laminated veneer lumber (LVL) and cross-laminated timber (CLT), all supplied by Xlam. At 98 meters (322 feet) wide, it will be the largest single-span timber arch hangar in the southern hemisphere and the first to achieve a 6-Star Green Star rating.

Jimmy Corric, NZ Strong’s pre-construction and innovation manager, told the New Zealand Herald last year that the design is attracting global attention. “The span is believed to be larger than the wooden hangar in Tillamook, Oregon,” he said. While steel is used in the front arches to support the door, “the remainder of the structure relies almost entirely on timber, with steel limited to base plates.”
