Ensuring that waste is managed and disposed of responsibly
Waste disposal takes many forms including direct discharge to land or water, and sludge disposal. Such wastes need to be managed in such a way that the adverse effects are minimised to protect the environment and human health.
Community and Public Health works with local and regional councils to ensure that both solid and liquid waste is disposed of in healthy manner to prevent:
- chemicals and pathogens contaminating drinking water;
- contamination of soil by heavy metals from industrial processes and surface runoff;
- creating favourable environments for disease-causing bacteria and viruses including bioaerosols;
- unpleasant or harmful odour problems; and
- unfavourable effects on Māori cultural values since they place high value on their land and water.
The Medical Officer of Health and Health Protection Officers have specific powers under the Waste Management and Minimisation Act 2008:
- Councils are legally required to consult with the Medical Officer of Health when preparing a Waste Management and Minimisation plan (Section 51); and
- Health Protection Officers have powers to serve notice on a Council to abate a waste nuisance (Section 55).
Waste reduction is something where we can all make a tangible difference – whether it is reducing single use plastic, recycling materials we use and using less disposable materials that end up in landfills.
Dealing with liquid waste products
The primary sources for liquid waste are:
- septic tanks from residential properties,
- reticulated wastewater systems including Wastewater Treatment Plants; and
- disposal of oils, fats and sludge from Offensive Trades such as fish cleaning, rubbish collecting and stock yards.

Dealing with solid waste including recycling
The primary sources of solid waste are domestic, commercial and industrial waste from processes and packaging, demolition material and organic materials.
Rubbish collection and disposal is primarily the responsibility of district and regional councils under the Local Government Act 2002 and the Resource Management Act 1991.

Government takes action on problem plastics
Beehive media release: 27th June 2021
The Government has delivered on its promise to phase out problem plastics and some single-use plastics by July 2025, Environment Minister David Parker announced today.
The plastics to be phased out will be:
- Hard to recycle food and drink packaging made from PVC and polystyrene and some degradable plastic products (such as oxo and photo degradable); and
- Single-use plastic items, including drink stirrers, cotton buds, single-use produce bags, cutlery, plates and bowls, straws and fruit labels.
“These types of plastics often end up as waste in landfills and cause pollution in our soils, waterways and the ocean. Reducing plastic waste will improve our environment and ensure we live up to our clean, green reputation,” David Parker said.
“Phasing out unnecessary and problematic plastics will help reduce waste to landfill, improve our recycling system and encourage reusable or environmentally responsible alternatives.
The plastics phase-outs will take place in three stages starting late 2022 for the easier to replace items.
How to live more sustainably
Waste management is a major challenge in NZ as three quarters of our waste that is sent to landfill is recoverable.
We can show love for our environment and our planet by living as waste-free as possible. We can also waste less money in the process!
- Choose products with compostable or biodegradable packaging – avoiding those with unnecessary or unrecyclable packaging.
- Use reusable bags and containers.
