Air Quality

Air quality in the West Coast region is generally good however over the cold winter months emissions from domestic heating increase and can cause a reduction in air quality. 

Air quality in the West Coast region is generally good however over the cold winter months emissions from domestic heating increase and can cause a reduction in air quality. Following some investigative monitoring in the early 2000's a permanent air quality monitoring site was established in the town of Reefton. The majority of larger towns on the West Coast are situated close to the coast and therefore benefit from a greater degree of air circulation which helps to distribute particulate matter such as PM10. Reefton is an inland town which has climatic, geographic and anthropogenic factors contributing to poor air quality during winter. The West Coast Regional Council is working with the Reefton community to work towards improvements in air quality for the town. For further information regarding air quality on the West Coast please contact the West Coast Regional Council.   

Regional Summary
PM10 at towns in this region

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 for air quality on the West Coast especially over the winter months when solid fuel burning for domestic heating increases. PM10 is currently monitored at one site in Reefton where, over winter, there can be a number of exceedances of the National Environmental Standard for PM10.

What is this graph showing me?

The graph shows the annual average or highest daily average PM10 concentrations for monitored town(s) in this region for the year selected. The PM10 concentrations are shown against the guidelines for air quality, and where concentrations exceed 100% of the guideline this can be a cause for concern, especially if this occurs on a frequent basis. (For a town that has more than one monitoring site, only one representative site is shown here).

What is this table showing me?

The table shows the annual average, and the dates of the highest and second highest daily average PM10 concentrations for monitored town(s) in the year selected. The 10-year trend indicates, in terms of PM10, whether the air quality has been improving, showing no measurable change, or declining over the last 10 years.
