Hazardous substances

The use of hazardous substances is primarily governed by the Hazardous Substances and New Organisms Act 1996 (HSNO).

Hazardous substances are often called dangerous goods or chemicals. Under HSNO, many substances that might not seem dangerous are termed 'hazardous'. For example, in large quantities, milk may not hurt people - but a large spill of milk into a stream could harm wildlife.

Chemical storage sites are scattered around the Wellington region, usually near areas of heavy industry. Explosives are used at quarries and are stored by the military. Chlorine is used in water treatment plants and swimming pools. Ammonia, solvents, caustic soda, corrosives and toxic substances such as lead are used in industry around the region.
