Mount Maunganui

The largest industrial area in the Western Bay of Plenty is centered around the Port of Tauranga at Mt Maunganui and Sulphur Point. There are a number of monitoring sites in this area looking at a range of contaminants. Some of these monitoring stations have recorded exceedances of the National Environment Standards for Air Quality for PM10 and SO2. More information can be found on our Mount Maunganui industrial area air quality page.

A recent emission inventory exercise by Wilton (2023) is available upon request from the Bay of Plenty Regional Council.

Town Summary
Air quality in this town

There are a number of dusty activities that operate in the Mount Maunganui Industrial Area including fertiliser plants, concrete manufacturers and dry bulk material distributors (such as those that distribute palm kernel).

While there are a number of monitoring sites in the Mount Maunganui airshed, the Totara Street site has been chosen for the representative Town Summary for its central location and as the longest data collection site in the area (since 2005).

    The table shows the proportions of the main sources of PM10, PM2.5 and nitrogen oxides (NOx) 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 NOx 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.

What is this graph showing me?

The graph shows the monthly average PM concentrations at one representative site in this town for the year selected. In many towns in New Zealand, PM peaks in the winter when air temperatures and wind speeds are lowest as more people heat their homes during colder weather, and still conditions mean that there is no wind to disperse the air pollutants.
