Changes to how hazardous substances are managed

New Zealand’s system for managing hazardous substances is changing.  The rules that govern the use of hazardous substances in the workplace are moving from the Hazardous Substances and New Organisms (HSNO) Act (administered by the EPA) into a new Health and Safety at Work (HSW) Act (administered by WorkSafe).

The changes are part of a wider effort by the Government to improve overall workplace health and safety. This page gives you details about what’s happening, and provides links to learn more.

Read information about the background to the reform and why changes are being made.
