Experience across New Zealand
Our environmental work is grounded in New Zealand sites, New Zealand soils and New Zealand consenting. Most of it starts the same way: somebody needs to know whether a piece of land is fit for what is planned for it, what the risk actually is, and what it will take to satisfy the council.
Recent work includes contaminated land assessments on a former industrial site at Hastings, preliminary and detailed site investigations on former horticultural land in Hawke’s Bay, a detailed site investigation at Gisborne, and environmental compliance monitoring and freshwater ecology for Waiū Dairy at Kawerau in the Bay of Plenty. We have also carried out contamination assessment supporting the redevelopment of Tolaga Bay Area School, and hydrocarbon and dairy effluent investigations on rural and industrial sites.

Contaminated land, from screening to sign-off
Contaminated land is handled inside this service rather than as a separate offering, so one team carries a site from the desktop review through sampling, risk assessment and remediation design to validation and the reporting a council needs before it will close a consent out. We scope the investigation to the decision being made. A straightforward residential subdivision should not attract the programme a former industrial or horticultural site needs, and we will say so early rather than bill for certainty nobody asked for.
