Reefton is a small town on the West Coast which, due to geographic, climatic and anthropogenic causes, suffers from poor air quality over the winter months. There has been a permanent monitoring site located in Reefton since 2006. The main source of PM10 is from domestic heating - contributing to 98% of daily winter PM10 emissions (Wilton, 2019). Small contributions come from industry, traffic and outdoor burning. The town is surrounded on three sides by hills which impede air movement. Cold temperatures and reduced air flow during winter can cause an inversion layer to form, restricting the movement of polluted air.

The table shows the proportions of the main sources of PM₁₀, PM_2.5 and nitrogen oxides (NO_x) in this town from home heating, industrial activities, outdoor burning and traffic. (Indoor, natural and shipping sources are not included in this breakdown).

These values come from 2013 data sourced from MfE’s data service. Consistent methodology was used to calculate these estimates of PM and NO_x emissions, which allows comparison between towns throughout New Zealand. Regional council or unitary authority published emissions information might differ if they were prepared in a different year or used another method. Contact your regional council or unitary authority for more information about PM and other emissions in your area.
