A successful and robust construction sector is central to New Zealand’s ability to address our infrastructure deficit and adapt to challenges such as climate change.

With New Zealand's leading team of construction law specialists, we assist clients to meet the challenges, take advantage of the opportunities, and anticipate the risks before they arise.

Our specialist lawyers advise across all stages of a construction project and have in-depth experience gained from many decades advising on major construction projects, across multiple sectors, in New Zealand. We also advise on significant international projects.

Our expertise includes advising on innovative methods of procurement and contract structuring, partnering, alliancing, and other collaborative working initiatives. A key speciality is advising on public private partnerships (PPPs).

Our work extends to all aspects of alternative dispute resolution, including mediation, adjudication under the Construction Contracts Act, expert determination and dispute review boards. This complements our extensive experience in traditional forums, such as arbitration and litigation.

Our experience covers both vertical and horizontal projects in all industry sectors, including telecommunications, roading and transport, water and waste water, solid waste, energy, tunnelling, and commercial buildings.
