Record breach for Invercargill air quality
Air quality in Invercargill over the weekend reached a new high, which is a new low when it comes to meeting the
government’s National Environmental Standard for Air Quality.
Saturday night’s exceedance was the highest recorded in Invercargill since 2012, and the 6th highest at the Pomona
Street site since monitoring began there in 2008.
The standards allow for one exceedance per year of the pollutant PM10, which is set at an average daily limit of 50
micrograms/m3. The exceedanceon Saturday reached 103 micrograms/m3 and was the fourth exceedance of the week.
Environment Southland air quality scientist Owen West said Invercargill has had 9 breaches of the NES so far this
winter. “The calm weather conditions would have had an impact in the weekend’s high recording of PM10 in Invercargill,
but other factors like outdoor burning on the edge of the city could also play a part,” he said.
Brochures ‘Breathe Easy… Change is in the air’ have been delivered to homes in the Invercargill and Gore airsheds in
June and outline the issues and options being grappled with in the review of the Regional Air Plan for Southland. These
issues include home heating options, outdoor burning, agrichemical and fertiliser use.

Environment Southland monitors air quality and reports on the results during winter. The built up urban areas of
Invercargill City and the Gore township are gazetted airsheds because they regularly exceed the national standards
during winter.
