Hazardous Substances

Many substances used in agriculture and horticulture are classed as hazardous substances, because the potential exists for these substances to harm people or the environment.   Such substances include agrichemicals, detergents, fertilisers, animal remedies, explosives, and fuels.  

Management of Hazardous Substances is shared between Environmental Risk Management Authority (ERMA) who administer the Hazardous Substances and New Organisms Act (1996) and Regional and District Councils under the Resource Management Act 1991.

ERMA sets controls for the use of hazardous substances with which uses need to comply.   The focus is on appropriate storage use and disposal of substances so that the risks are adequately managed.   Such controls may include handling and storage requirements and 'Approved Handler' requirements.

Some substances may have long term effects of land and care is needed to ensure that problems are not being created for future generations.

The introduction of New Organisms, including Genetically Modified Organisms (GMO's), are managed by ERMA under the HSNO Act.   The NZ Food Safety Authority also has responsibilities for carrying out safety assessments of foods which contain GMO's.

The framework identifies a range of tools to assist compliance with HSNO regulations.
