Tasman HAIL Sites

This section deals with land which may have been included on the Hazardous Activities and Industries List. It explains the Council's role and the responsibilities of the landowner and provides links to further information.

Hazardous Activities and Industries List

A site may become hazardous because of substances stored, used or manufactured there, particularly if spilt or dumped inappropriately. In the Tasman District land used for the following activities is considered particularly vulnerable. These identified land uses are based on a national Hazardous Activity and Industries List (HAIL) produced by the Ministry for the Environment. 

  • Chemical timber preservation (timber treatment sites)
  • Landfills and historic rubbish tips
  • Pre 1970s orchard land
  • Sheep dips and slipways
  • Underground fuel storage facilities
  • Pesticide and agrichemical manufacturing and storage
  • Industrial land (engineering works, scrap yards etc.)

Many of the contaminants of concern such as pesticides, pentachlorophenols (PCP), benzene, arsenic or heavy metals can cause cancer or other long term illnesses. Some of the contaminants can concentrate in the food chain, poisoning fish, birds and ultimately, the people and other animals that eat them.

Liability For Contamination

The property owner is liable for any contamination on the property, even if that contamination was caused by a previous landowner. The costs of the site assessment are paid by landowners, however, the Council may be able assist you in investigating and cleaning up contamination.


HAIL Register

Council's inventory of known contamination and land where hazardous activities and industries are, or have, been undertaken.

Historic HAIL Sites

Agricultural and horticultural practices have included the use of various pesticides and agrichemicals. Some of these chemicals can persist in the environment and hazardous residues can build up and remain in soils.


The Council's Role

The Council has a responsibility to investigate and control any adverse effects from hazardous substances or contamination during development, subdivision or use of land. The risks and the way potentailly hazardous sites are managed varies. Land uses and subdivision on HAIL sites are either controlled through the Tasman Resource Management Plan, or the National Environmental Standard for Assessing and Managing Contaminants in Soil to Protect Human Health.  In Tasman District sites are generally managed by:

  • Maintaining an inventory of the status of HAIL sites
  • Restricting the range of land uses and activities, such as buildings or earthworks that are able to occur at potentially hazardous sites.
  • Controlling subdivision of HAIL sites.
  • Capping hazardous soil to isolate the contamination from rain, wind and people.
  • Treating or removing the most hazardous soils.

Many of the activites above will require resource consent and the Council recommends speaking with the Duty Planner or Resource Scientist - Contaminants  prior to lodging an application for land use change or subdivision involving land that is or may be hazardous.
