Auckland Airport’s $2.2 billion terminal redevelopment is currently one of the most ambitious infrastructure projects in New Zealand’s history. As the most significant investment in the airport’s 50-year history, the new domestic terminal is being built with a focus on sustainability and innovation. The development aims to meet the growing demands of passengers while reducing the environmental footprint of aviation.
Sustainable Materials at the Heart of the New Terminal
In an effort to lead the way in sustainable aviation, the new terminal will feature cross-laminated timber (CLT) for its subfloor. Unlike traditional concrete, mass timber provides a lower carbon alternative. The decision to opt for CLT highlights Auckland Airport’s commitment to low-carbon materials and its role in sustainable construction. The installation process has been streamlined by the use of an innovative rail system, designed to allow the terminal to be built in a live environment while maintaining full operation of the international terminal.
In a statement, Hawkins, New Zealand’s largest construction firm and the contractor leading the development, explained that challenges such as temporary waterproofing and high-voltage service separation had been overcome. They are also focusing on the integration of new mechanical and power services to the international terminal.
Key Features of the Terminal Development
The new terminal is a major part of the $2.2 billion Auckland Airport redevelopment project. It will introduce 12 jet aircraft gates, increasing the airport’s seat capacity by 26% and providing more than 20,000 passenger spaces daily. The terminal will serve larger aircraft that fly between Auckland and other major centres in New Zealand.
Carrie Hurihanganui, CEO of Auckland Airport, highlighted that the terminal will also include several enhancements aimed at improving the travel experience. “Building in a live operating airport environment is no small task,” Hurihanganui noted. “While we’re focused on minimising the impact on travellers as much as possible, we know change is disruptive, and we thank travellers for their patience as the build progresses.”
The terminal’s design will draw inspiration from the Manukau Harbour, volcanic stone fields, and nearby mountains. Its simple yet robust exterior will be made from tray-profile steel, with timber accents and a mix of carpeted and rubber flooring indoors. The design is intended to create a relaxed and intuitive experience for travellers. Additionally, all-electric heating and cooling systems will be integrated into the terminal, further reducing its carbon footprint.
Focus on Passenger Experience and Efficiency
The new terminal will aim to provide a seamless travel experience. Passengers will benefit from a short five-minute indoor walk between gates, eliminating the need for the current outdoor “green line” walk or inter-terminal bus service. For passengers transferring between domestic jet and international flights, the new terminal will enable easier access, thanks to its integrated layout.
The design will include check-in kiosks and automatic bag drop systems, with the future potential for biometric technology to streamline the check-in process. The airport also plans to reduce queue wait times to less than 4 minutes for self-check-in and bag drop, 7.5 minutes or less for security, and a quick 15-minute baggage arrival from first to last bag. To ensure comfort, device charging points will be available in 50% of seats in the pre-departure area.
Improving Baggage Handling and Accessibility
The baggage reclaim area in the new terminal will be substantially larger than in the current domestic terminal. With 180m of belt space, the new system will increase capacity by 70%, significantly improving efficiency. In addition to practical upgrades, the terminal will provide a dedicated faith space and a low-sensory room for passengers with specific needs.
The $2.2 billion terminal redevelopment will also feature a total of two baggage reclaim areas, each catering to increased foot traffic and baggage handling. This will allow Auckland Airport to provide better service for the growing number of travellers expected by the end of the decade.
Construction Challenges and Timelines
The construction of the new Auckland domestic terminal is progressing steadily, with Hawkins overseeing the installation of more than 600 steel piles, each driven 35 metres into the ground to support over 6,000 tonnes of steel, concrete, and timber. The challenges of building on an active airport site have not been underestimated. Hawkins has faced everything from high-voltage service separation to designing bespoke roof cowls for the site.
The airport anticipates completing the terminal by 2028–2029, with the facility set to provide enhanced capacity and a future-focused experience for passengers. “Choosing wood for the subfloor instead of concrete reflects a preference for low-carbon materials and supports sustainable aviation,” said Scott Tasker, Auckland Airport’s Chief Customer Officer.
Looking Ahead
Once complete, the new terminal will accommodate up to 20,000 passengers daily, significantly increasing processing capacity by 44% and improving the flow of passengers throughout the terminal. The facility is designed to handle the increasing demands of aviation and to support sustainable aviation practices well into the future.
With the terminal set to open in 2028–2029, it will mark a significant milestone in Auckland Airport’s history, not only enhancing passenger experience but also showcasing sustainable construction practices that are setting the standard for future airport developments worldwide.
