Quick answer
What does Cities with cleanest air in New Zealand show?
Pukekohe, New Zealand has the lowest pm2.5 — annual mean of the 12 cities compared: 5.15 µg/m³ (LAWA Air Quality Dataset (2016–2025), daily PM2.5 observations, 2023-12-31).
How this list is built
Every row is a published pm2.5 — annual mean observation measured in µg/m³, ranked lowest first. The values were observed between 2012 and 2024. A place appears only when it publishes this exact metric, so an absent place means missing data rather than a low value. Only published cities with at least 20,000 residents and city-level observations qualify.
- Compare the displayed value, unit, source date and geographic grain together.
- A city label does not change a regional observation into a city measurement.
