What Airey does

Airey Consultants Ltd is a privately-held New Zealand engineering consultancy founded in 1965 by Don Airey in Pukekohe. Operating as an integrated practice of engineers, construction professionals, and advisers, the firm delivers civil, structural, and fire engineering services across nine market sectors — residential, commercial, industrial, retirement villages, horticulture, institutional, land development, marine and coastal, and specialty structures. Service scope spans from feasibility and resource consenting through detailed design, contract administration, and construction monitoring. The firm holds specialist domain positions in New Zealand canal engineering (Pauanui, Whitianga, Marsden Cove) and marina and coastal development, with 30+ years of accumulated experience in those niches.

The business is structured around director-led project delivery, with each engagement overseen by a director supported by handpicked engineers, and is distinguished by exceptionally long staff tenure — multiple directors have served 25–37 years. Airey operates from three offices (Takapuna, Botany, and Queenstown) with 60+ employees, having expanded into Queenstown in 2006 and consolidated civil engineering capability in Botany following the 2020 acquisition of Stroude and the 2021 acquisition of Morconsult. The firm has served multi-decade enterprise clients including Metlifecare, Hopper Developments, Fulton Hogan, NZ Chemical Care, and Remarkables Park, and contributes to marquee New Zealand infrastructure including the Auckland Harbour Bridge Skypath early design and the award-winning Barry Curtis Park Playground (2026 Recreation Aotearoa Playspace of the Year).

Revenue is generated through project-based professional services billing, with payment terms requiring settlement by the 20th of the month following invoice and overdue interest charged at 2% above BNZ commercial rates. Go-to-market is sales-led and direct, targeting property developers, construction companies, government agencies, architects, and individual landowners through referrals, project proposals, and six decades of relationship continuity. Pricing is not publicly disclosed. Ownership remains with the directors and senior leadership team; there is no external institutional or private equity backing.

Direct peers

• Beca: New Zealand's largest employee-owned engineering and consultancy firm, offering civil, structural, and multi-disciplinary engineering across infrastructure, buildings, and industrial sectors. Most directly comparable ANZ peer given its NZ roots and broad consultancy model.
• Holmes Group: NZ-based structural and civil engineering consultancy with a similarly mid-sized, specialist profile. Comparable as a domestic structural/civil peer serving NZ commercial, residential, and infrastructure projects.
• Dunning Thornton: NZ structural engineering consultancy with a comparable boutique, design-led approach to complex buildings. Comparable as a domestic specialist peer competing for architectural and developer-led projects in the NZ market.
• Tonkin + Taylor: NZ-headquartered environmental and engineering consultancy with strong civil, geotechnical, and coastal/waterfront expertise. Closely comparable to Airey on coastal/marine engineering and NZ land development work.

Broad incumbents

• WSP: Global professional services consultancy with major NZ operations across property, transport, and environment. Overlaps with Airey on land development and infrastructure projects as part of a much wider portfolio.
• Stantec: Global engineering, architecture, and environmental consulting firm with established NZ presence in water, buildings, and community development. Comparable on land development and infrastructure work but operates at far larger scale.
• Aurecon: Global engineering and infrastructure advisory with deep ANZ roots and significant NZ presence. Competes with Airey on multi-disciplinary NZ projects but offers far broader global scale and service breadth.
• AECOM: Global infrastructure consultancy with NZ offices delivering civil, structural, and environmental engineering. Competes for larger NZ projects but offers substantially broader global capability and scale.
