National Environmental Standards for Air Quality
The Ministry for the Environment (MFE) introduced National Environmental Standards for air quality in 2004. The regulations set ambient standards for five pollutants: carbon monoxide, sulphur dioxide, nitrogen dioxide, ozone and PM10. The National Environmental Standards (NES) also prohibit certain activities and set emission standards and efficiency criteria for wood burners used for household heating.
Under the NES Regional Councils must monitor these five air pollutants and publicly notify any exceedances. The implementation of NES also requires Regional Councils to designate areas (airsheds) where air quality has been adversely affected.
Using research carried out by the National Institute of Water and Atmospheric Research (NIWA), the Regional Council identified five areas in Northland which are suspected of reaching or exceeding the NES. The five airsheds in Northland include Whangārei City, Marsden Point, Kaitāia, Kerikeri and Dargaville.
An online map, interactive map is available for you to check if your property is in an airshed.
