2016-2023: New Zealand air pollution levels drop, except in Tokoroa, benefiting public health.

New Zealand has seen significant decreases in air pollutant levels from 2016 to 2023, with particulate matter (PM10 and PM2.5) declining at many monitoring sites, and nitrogen dioxide (NO2) reducing at 99 out of 114 sites. These reductions can benefit public health by lowering risks of respiratory and cardiovascular issues. However, Tokoroa continues to struggle with high pollution levels due to factors like poor home insulation and wood burning practices.
