Purpose of collection
The Ministry for the Environment and Statistics New Zealand commissioned NIWA to produce a report that provides information for New Zealand’s Environmental Reporting Series: 2014 Air domain report. This report provides the methodology and results for the national air domain indicators – on-road vehicle emissions, annual average PM10, and health impacts due to exposure to PM10. It also includes information on natural sources of pollutants, and the influence of meteorological conditions on air quality.
