The Ministry for the Environment and Stats NZ have published the Our air 2021: preliminary data release
We are currently working to revise the Our air 2021 report to incorporate analysis of the World Health Organization (WHO) 2021 air quality guidelines
that were released on 23 September 2021. The revised report will be released on 10 December 2021.
Our air 2021: preliminary data release shows that air quality has generally improved at most sites and across many of the indicators used. However, we expect
the number of locations with air quality concerns to increase as we revise the Our air 2021 data against the new WHO air quality guidelines.
