Air

The Waikato region generally enjoys good air quality, but in some areas air pollution can build up. This happens mostly in our inland city and towns.

Visibility monitoring in the Hamilton Basin shows that visibility varies a lot from day to day. On some days Mount Ruapehu (170 km away from Hamilton) is visible from some of the higher buildings in Hamilton. On other days, Mount Pirongia (30 km away) is not.

What affects air?

Most air pollution comes from localised point sources such as from large industries and non-point sources such as domestic heating and vehicles.

Air quality declines as:

  • our population increases
  • we use more resources
  • we increase industrial activity.

Home fires, outdoor burningmotor vehicle emissions, industry and livestock farming are all activities that affect air quality in the Waikato region. Air pollution can also come from natural sources such as from geothermal areas, salt spray and plant pollen.

In a 2000 survey 23 percent of people living in the Waikato felt that vehicle emissions damage air quality. This was much higher in Hamilton where 36 percent mentioned vehicle emissions. Industrial emissions were the most commonly mentioned activity damaging air quality in South Waikato, Taupo and Otorohanga district council areas.

Keeping our air clean

Waikato Regional Council helps protect and improve air quality in the region. We monitor several important air contaminants:

We require resource consents for activities that might release a significant amount of contaminants into the air. Resource consents set conditions on discharges to air that prevent or limit unwanted effects on air quality.

We work with communities and businesses, helping them learn more about what they can do to help improve air quality. We also support industry-based guidelines and codes of practice that help reduce air pollution.
