Waste management
Waste disposal takes many forms including direct discharge to land or water, and sludge disposal. Waste disposal needs to be managed to protect the environment and reduce negative health effects.

Reducing waste is something everyone can do
Reducing waste is something where we can all make a difference. Whether it is reducing single use plastic, recycling materials we use and using fewer disposable materials that end up in landfills.
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.

Sources of waste
The primary sources of solid waste are:
- domestic, commercial and industrial waste from processes and packaging
- demolition material
- 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.

The primary sources for liquid waste are:
- septic tanks from residential properties
- reticulated wastewater systems including wastewater treatment plants
- disposal of oils, fats and sludge from offensive trades such as fish cleaning, rubbish collecting and stock yards.
The National Public Health Service makes sure waste is managed responsibly
The National Public Health Service works with local and regional councils to make sure both solid and liquid waste is managed and disposed of in healthy manner. Their input in waste management and minimisation plans helps prevent:
- water contamination from chemicals and pathogens
- soil contamination 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
- unfavourable effects on Māori cultural values since they place high value on their land and water.
The Waste Management and Minimisation Act 2008 states:
- Councils are legally required to consult with the Medical Officer of Health when preparing a Waste Management and Minimisation plan (Section 51)
- Health Protection Officers have powers to serve notice on a Council to abate a waste nuisance (Section 55).
