New Zealand

Mott MacDonald's work on projects in New Zealand dates back over 40 years. Today we're providing leading-edge services in areas as diverse as buildings, transport, water and project management, with involvement in nationally significant infrastructure development.


Our experts are providing a broad range of services for the Auckland City Rail Link and we've undertaken a feasibility study for a combined road and rail tunnel across Auckland Harbour. The country’s largest ever infrastructure project, the NZ$4-5 billion Waitemata Crossing will ensure the ongoing growth of Auckland as a world-class city.

Built environment

We are the leading multidisciplinary buildings consultant in the country, with specialisms in structures, facades, building services and building sciences. Our projects range from the tallest building in New Zealand – 85 Customs Street, under construction, to the multi-billion-dollar expansion of Auckland Airport.

With a focus on aviation, metros, sports, commercial buildings, tertiary education and health, we have delivered design services for major projects. Key examples include Auckland Central Rail Stations, Auckland Stadium, Burwood Hospital Christchurch, 45 Queen Street Office Tower and the University of Auckland Science Centre.


Our water team has built on the expertise provided through our acquisition of specialist water technology and consulting company, AWT. We offer technical solutions across the project cycle and our key services include network monitoring, project planning and management, modelling, design, commissioning and optimisation.

We undertook the design for the $80M expansion of the Rosedale wastewater treatment plant and are working on implementing thermal hydrolysis technology to improve the plant. Watercare, the owner of the plant, is working towards an energy neutral installation. Our water treatment experience extends to the implementation of a NZ$20M membrane water treatment plant for Taupo to remove arsenic from the source water.

We’re utilising our skills in data management and analytics through our own application, Moata, on Auckland’s safe swim initiative. This application uses billions of data points from multiple sources to provide predictions around water quality and safety for the beaches across Auckland. In Christchurch City this platform has been used to monitor the effectiveness of the wastewater network to assist the rebuild project following the earthquakes of 2011.
