The most significant air pollutant in New Zealand are small airborne particles in our air (known as particulate matter). Particulate pollutants are of most concern in New Zealand because of their high concentrations in some of our towns. Exposure to high levels of airborne particle pollutants has the potential to cause respiratory and cardiovascular issues. View a factsheet on why air quality is important here.
PM10 is the main concern in Rotorua. It can have short- and long-term health effects. Council reports on annual and daily PM10 concentrations every year. Other contaminants include urban open burning, dust, agrichemical spraying and methyl bromide use at the Port of Tauranga.
