Extract:

Summary

• No breach of national air quality standards occurred in December 2023.
• The Khyber Pass Road and Customs Street sites recorded the highest levels of NO₂ and SO₂ concentrations respectively in December 2023.
• As in previous years, from January to December, city centre sites recorded the highest levels of particulate matter, likely due to traffic and construction activities.

It is important to note that air quality at a monitoring site can vary from year to year due to weather and other influences (See Auckland air quality report, October 2021). For a brief short-term trend analysis of key pollutants concentration changes, please see Table 2.
