Airport projects are like a puzzle with many moving parts, and advisers need to understand how those parts interconnect when supporting specific projects. It is equally important to ensure alignment across the various stakeholders, as well as separate contractors and project managers involved in delivery.
Wynn Williams advises on many infrastructure projects in live operating environments with stringent health and safety, and security requirements. Airports sit at the highest end of that spectrum, particularly for airside projects. Each airport has its own comprehensive health and safety plans, and contractors must dovetail into those plans, especially when undertaking work airside.
When acting for airports, advisers also need to consider the requirements of a wide range of stakeholders, including the use of airside space by commercial air operators, private users and emergency services, both on the ground and in the air. While there is often a main contractor, there may also be several separate contractors engaged directly by the principal. As lawyers, our role is to ensure that the contract structure accurately reflects what is happening on the ground across several different entities.
Paula Nicolaou, Wynn Williams’ front-end Construction Partner, has worked with airports on both airside and non-airside projects. She has supported these entities in adopting the NZS 391X suite of standard form construction contracts, with targeted project-specific amendments. Starting from a familiar contractual framework provides a shared baseline with the construction industry for time, payment, variations and risk allocation, which can reduce transaction friction and support efficient delivery.
Nicolaou and the team help to shape contract settings that reflect the realities of construction within an operating airport environment. This includes tailoring NZS 391X–based contracts to address airside and non-airside works, access constraints, sequencing challenges, and clear and workable processes for change. The company’s objective when working with internal airport teams is to help put in place a robust framework capable of accommodating change as the project progresses.
Projects combining airside and land-based construction bring familiar pressure points, including variable ground conditions, weather and programme risk, tight working windows, and coordination across specialist contractors, all within a public-facing environment where even small works can cause disruption. In that context, clear drafting is critical, particularly when assessing whether changes constitute variations, how time relief should be evaluated, the evidence required to substantiate cost, and how changes are priced and approved.
On complex multistage programmes, clarity and momentum are often more valuable than contractual complexity. Practical disciplines, such as timely notices, clear variation pathways, agreed records for time and cost, and early escalation of issues, help to keep the programme moving when scope or sequencing changes.
As with all projects, issues will arise. Recent market volatility has reinforced the value of contract settings that can absorb change without losing momentum. During planning and negotiation, fuel price increases linked to conflict in the Middle East created cost pressure in both the New Zealand and international markets, and became a live issue for delivery planning. Addressing that risk up-front through a targeted and transparent mechanism for defined fuel-related cost movements can help keep pricing assumptions realistic and fair between the parties, reduce dispute risk, and support progress as conditions shift.
Successful delivery on complex airport projects depends as much on the legal and commercial framework as it does on physical execution.
As airports and other transport hubs across Aotearoa New Zealand focus on lifting capacity and resilience, careful contract structuring, deliberate risk allocation and disciplined administration remain critical.
In working with airports and other transport-focused clients, the Wynn Williams team provides practical legal support to help projects progress with confidence in a challenging operating environment.
