The Hazardous Activities and Industries List (HAIL) is a compilation of activities and industries that are considered likely to cause land contamination resulting from hazardous substance use, storage or disposal. The HAIL is intended to identify most situations in New Zealand where hazardous substances could cause, and in many cases have caused, land contamination. This list is determined by the Ministry for the Environment (MfE)
The HAIL groups similar industries together, which typically use or store hazardous substances that could cause contamination if these substances escaped from safe storage, were disposed of on the site, or were lost to the environment through their use.
The fact that an activity or industry appears on the list does not mean that hazardous substances were used or stored on all sites occupied by that activity or industry. Nor does it mean that a site used by that industry will always have hazardous substances present in the land. The list just highlights that there is a greater probability of site contamination occurring than for other uses or activities.
