Air New Zealand Hangar 4

Project Overview
Air New Zealand’s Hangar 4 is the Southern Hemisphere’s largest single-span timber aircraft hangar, designed to simultaneously accommodate a widebody Boeing 787-9 Dreamliner and two Airbus A320/A321 aircraft. The facility includes hangar space alongside workshops and engineering areas, all designed with sustainability, operational efficiency, and safety in mind.

KOROK’s Role
KOROK Building Systems supplied KOROK® External Wall Systems for Hangar 4, delivering a complete solution for fire-rated, acoustic-rated, and weatherproof external walls. These systems were essential for providing safe, durable, and efficient separation across hangar and workshop areas, while withstanding New Zealand’s unique environmental conditions.

Project Highlights

• Panels integrated seamlessly with the massive timber trusses, minimizing additional structural load.
• All-in-one design simplified construction and accelerated the project timeline.
• Fire and acoustic performance created a safe and productive working environment for Air New Zealand engineers.

Outcome
KOROK® External Wall Systems and 78mm Colour Panels supported Hangar 4 in achieving world-class standards in fire safety, acoustic separation, and weather resilience. The lightweight, durable, and efficient solution complemented the innovative mass timber construction, helping create a safe, functional, and sustainable aviation maintenance facility.

Products Used

• KOROK® External Wall Systems: All-in-one solution for external walls, offering fast installation, fire and acoustic protection, and weatherproof durability without the need for cranes or engineered slabs.
