Health and Air Pollution in New Zealand (2012) (HAPINZ)

Purpose

A Health Effects Model allows end users to run scenarios to undertake sensitivity testing to test the effects of different assumptions, evaluate the effects of population and emissions trends, or review the effectiveness of different air quality management options.

Description

A Health and Air Pollution in New Zealand Study was  first carried out in 2007 to comprehensively assess the air pollution health effects in New Zealand.

An Updated Health and Air Pollution in New Zealand (Updated HAPINZ) study was commissioned in 2010 by the Health Research Council of New Zealand in partnership with the Ministry for the Environment, Ministry of Transport, New Zealand Transport Agency with in-kind support from the Ministry of Health and the legacy Auckland Regional Council. This resulted in an updated report on the health effects and the development of two assessment models based on an Excel spreadsheet. The full history and documentation from these studies are available on the HAPINZ website.

Air pollution in New Zealand is a complex mixture of gases and particles. The assessment by the Updated HAPINZ research team involved particulate matter less than 10 micrometres in size (PM10) as the majority of health effects in New Zealand are associated with this pollutant.  The updated study sought to identify the effects of air pollution throughout New Zealand and link these effects to the various levels of air pollution. It also sought to correct a number of errors that had been identified with the 2007 report in the review carried out in 2010.  It is anticipated that the results obtained from the updated study will increase understanding of the links between sources of pollution, impacts on human health and the estimated costs of these impacts.

The Health Effects Model, based on an Excel spreadsheet,estimates health effects and social costs associated with air pollution for 2006. The model uses annual average annual average PM10 concentrations for each census area unit (CAU) across New Zealand and determines health effects and social costs associated with a range of air pollution sources, including:

  • domestic fires used for home heating
  • motor vehicles
  • industry
  • open burning
  • natural sources, e.g. sea spray and windblown dust.

The Model allows end-users to output results nationally, regionally, by Territorial Local Authority, by Statistics NZ urban areas, or by airshed. End-users are also able to run scenarios for comparison with the base case, by selecting from a range of plausible input values of population, exposure and epidemiological exposure-response functions.

The scenario option can be used to undertake sensitivity testing to test the effects of different assumptions, evaluate the effects of population and emissions trends, or review the effectiveness of different air quality management options.

Data from the model can be exported and processed in GIS to provide spatial analysis and visualisations of the data.

Associated Case Studies

HAPINZ - Christchurch Pilot Study

The aim of this study was to assess the viability of their methods through an initial pilot study; in this case Christchurch City, with the objective of refining and improving the methodology throughout the study in anticipation of wider applications.
