Subdivision & Contaminated Land

Check to see if land is potentially contaminated ...

Since Regional Councils started to identify land that could be contaminated by chemicals or hazardous substances (called “Hazardous Land”) we have had instances where clients subdividing in areas of Tauranga that used to be orchards have had to undertake expensive soil testing and had specific conditions imposed in subdivision consents.

Hazardous land uses include:

  • orchards, market gardens and other horticultural land where chemicals may have been stored or spraying may have occurred;
  • service stations and other underground or above-ground storage of hazardous substances;
  • motor vehicle workshops, timber treatment sites and some industrial sites.

Before subdividing (or if you have concerns about your property) check to see if it is on a Hazardous Activities and Industries List (HAIL).

The list shows land where activities or land uses have been carried out that may cause contaminated land.  In addition, the HAIL activity may only have occupied a small part of the site.

If you believe that your property has been incorrectly identified as a HAIL site you will need to gather as much information as possible to determine whether your land is contaminated, such as instructing an experienced contaminated land (or environmental) consultant to carry out an initial site investigation. You should then present this new information to Regional Council to avoid problems in the future either when you come to sell or if you want to subdivide.
