Hazardous Substances New Organisms (HSNO) Act

The Environmental Protection Authority (EPA) administers HSNO legislation. However, there are a number of agencies responsible for enforcing the HSNO Act.

These include Queenstown Lakes District Council who has been contracted by the Department of Labour, to enforce the provisions of the Act in any work place.

Your HSNO Obligations

All hazardous substances are subject to the Hazardous Substances and New Organisms (HSNO) Act

This could mean that you have to obtain test certificates to confirm your site is to the required standard and that staff are trained. A Test Certificate is a document that shows a site (including equipment) or a person meets the standards for safe use of a hazardous substance. The certificates are issued by an EPA approved test certifier.

There are specific requirements to be followed to safely manage hazardous substances’. Responsibility for HSNO rests with the “person in charge”, who can be the owner, lessee, sub-lessee, or the occupier of the premise.
