Resource Management (National Environmental Standards for Air Quality) Regulations 2004 [New Zealand Legislation website].

In force from

  • 8 October 2004 

It was amended following an evaluation and public consultation process over 2009 – 2011.

The amended NES came into effect on 1 June 2011.

Current proposed amendments

In 2020, the Government proposed amendments to some provisions of the National Environmental Standards for Air Quality (NES). Consultation on the proposed amendments was held from February to July 2020.

The aim of these amendments is to better control the release of fine particles into our air. The proposed amendments also include controls on mercury emissions. These would help us meet our obligations under the Minamata Convention on Mercury.

Timeframes for the proposed amendments to the National environmental standards for air quality are subject to the release of new evidence. This includes the updates to the World Health Organisation guidelines and the Health and Air Pollution in New Zealand study. These are expected to be released mid-late 2021.

What they cover

The NES are made up of 14 separate but interlinked standards including:

  • seven standards banning activities that discharge significant quantities of dioxins and other toxics into the air
  • five standards for ambient (outdoor) air quality
  • a design standard for new wood burners installed in urban areas
  • a requirement for landfills over 1 million tonnes of refuse to collect greenhouse gas emissions.

Requirements for councils

Regional councils and unitary authorities are responsible for managing air quality under the Resource Management Act. They are required to monitor areas where air quality is likely or known to exceed the standards.
