Some historic and current activities can leave a legacy of contamination because of the way hazardous substances are used, stored or disposed of.
As land is developed in New Zealand, it is important to know where contaminated (or potentially contaminated) land is located. Then if a change to a more sensitive land use is proposed (e.g. industrial to residential), the risk to potential users can be assessed.
We keep a record of sites where hazardous substances are or have been used, stored or disposed of on our Selected Land Use Register (SLUR). Some of these sites are things like service stations, paint manufacturing plants, landfills, former gasworks and airports.
It is important to note that while most registered sites have a verified history of a hazardous activity having taken place, they are not actually contaminated.
We regularly update the SLUR with new information from district and city councils, internal desktop investigations, independent consultant reports and local knowledge.
