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.

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!
- Find out how to reduce your food waste, including composting (Love Food Hate Waste).
- Find out what types of plastics and paper products can be recycled. Some types are easier to recycle than others.
- Choose products with compostable or biodegradable packaging – avoiding those with unnecessary or unrecyclable packaging.
- Use reusable bags and containers.

Reducing waste: A more effective landfill levy
New Zealand has a waste problem. We are disposing more and more waste into landfill.
The landfill levy is one of the most effective tools we have to help us change. The Government is proposing to increase the levy and apply it to more landfill types.
The Ministry for the Environment is keen to get your feedback on the proposals.
The consultation closes on Monday 3rd February 2020.
