Water & Wastewater

Managing water resources is a key long-term priority for New Zealand. We have considerable industry experience in water, wastewater, and stormwater, having been involved in many of the most significant projects in New Zealand in recent years.

We work with our water and wastewater clients, including councils, CCOs, utilities, or major corporate water users, as business partners. We work closely with professionals at all levels of the water and wastewater industry in order to achieve effective results for clients, whether we are advising on projects or regulation or resolving major litigation.

Our expertise spans resource management, construction, regulatory, contract, and commercial law.
