Correction: 6 June 2023
We have corrected content and five figures throughout the report which cite trend data from Stats NZ air indicators. We have also corrected rounding errors for content relating to PM10 state. In October 2022, Stats NZ updated the trend methodology for the following air indicators: Carbon monoxide concentrations, Ground-level ozone concentrations, Sulphur dioxide concentrations, Nitrogen dioxide concentrations, PM₁₀ concentrations, and PM₂.₅ concentrations. Therefore, we are updating the related data in this report to ensure consistency with those indicators.
