It is the role of our regional councils and unitary authorities to monitor air quality in their regions. Access regional data from this page.
Air quality monitoring data
See the data on the LAWA website.
Regional councils monitor air quality in areas (airsheds) where air quality has or could breach the National Environmental Standards for Air Quality (Air Quality NES)
Airsheds are published in the New Zealand Gazette.
There are currently 72 airsheds nationally. All but one of these areas has the potential to breach the particulate matter (PM10) standard.
The remaining airshed (Marsden Point in Northland) has the potential to breach the sulphur dioxide standard.
In most cases an airshed is confined to a single urban area but it may also be a combination of towns (eg, the Otago 1 airshed combines Alexandra, Arrowtown, Clyde and Cromwell).
