Waste management

Solid waste

The primary sources of solid waste are:

• domestic, commercial and industrial waste from processes and packaging
• demolition material
• organic materials.

District and regional councils have the main responsibility to collect and dispose of rubbish. This is under both of the following Acts.

• Local Government Act 2002 — New Zealand Legislationexternal link
• Resource Management Act 1991 — New Zealand Legislationexternal link
• Council websites – LGNZexternal link

Liquid waste

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.

We can all make a difference and reduce waste. Whether it is:

• reducing single use plastic
• recycling materials we use
• using fewer disposable materials that end up in landfills.

Three quarters of our waste sent to landfills is recoverable. Reducing waste is a practical way to protect our environment.

The National Public Health Service works with councils to make sure both solid and liquid waste is managed and disposed of in a healthy way. 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
• 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 fix a waste nuisance (Section 55).
