Providing advice and information on hazardous substances
Effective management of hazardous substances throughout their lifecycle is necessary to avoid adverse health effects from either direct exposure or environmental contamination. Community and Public Health’s role relates to situations where there exists a need to protect public health, not withstanding other agencies’ responsibilities.
Contact your local Community and Public Health office for information and advice on hazardous substances including:
- Asbestos;
- Lead and lead poisoning; and
- Vertebrate toxic agents (VTAs).
Under the Hazardous Substances and New Organisms (HSNO) Act, other agencies also have substantial hazardous substances roles and responsibilities including:
- WorkSafe NZ is responsible for ensuring that the provisions of the Act are enforced in any workplace. They are a division of the Ministry of Business, Innovation and Employment.
- Councils are responsible for ensuring that the provisions of the Act are enforced in or on any premises situated in their district, other than those premises specified in section 97 HSNO Act as being the responsibility of another agency.

How to stay safe with home and gardening products
Many of the everyday products you use at home contain chemicals that fall into the category of ‘hazardous substances’ – including toothpaste, dishwashing powder, and paint.
Weed-killers, pest sprays, fertilizers and many other gardening products are also considered ‘hazardous substances’.
Labels on these products explain the physical, health and environmental risks that you need to be aware of so that you can use, store and dispose of them safely.

- Get some simple tips for how to stay safe when using gardening products.

Call 111 immediately if a person is not breathing or is unconscious.
Looking at the hazardous effects of radiation
The National Centre for Radiation Science is the lead public health agency for radiation issues. Community and Public Health also carries out some activities, including:
- responding to inquiries and complaints;
- reviewing resource consent applications relating to ionising and non-ionising radiation; and
- responding to radiation emergencies if necessary.
Ionising radiation is radiation which has sufficient energy to knock electrons out of (ionise) atoms. X-rays and gamma rays are types of ionising radiation, as are the particulate radiations of alpha and beta particles that are found in some types of nuclear decay. Ionising radiation is what the general public regards as ‘radioactive’.
Non-ionising radiation includes electromagnetic fields in the form of extremely low frequency fields, visible light (including lasers), microwave (including microwave ovens and cell-phone transmissions), radiofrequency fields, ultra violet and infrared.
