This report presents an analysis of airborne particle samples from an ongoing sampling programme collected from 2006 to 2013 at five ambient air quality monitoring sites across the Auckland region. Exposure to air pollution from airborne particles can result in significant adverse health effects for the resident population. Understanding the composition and identifying the sources of air pollution is vital for effective air quality management and policy implementation.

The main objectives of the study were to:
• identify the sources contributing to air pollution episodes;
• estimate the contribution of sea salt and other natural particulate matter sources to ambient concentrations;
• estimate the contribution of secondary particulate matter sources to ambient concentrations;
• distinguish between the contribution of home heating and motor vehicle emission sources;
• determine the variation of source contributions by season;
• examine inter-annual variations in source contributions;
• observe the trends in source contributions over time.
