Environmental Health Indicators

Friday 9th June 2023



Environmental health indicators (EHIs) are measures that summarise the relationship between the environment and health. Their main functions are to:

  • Monitor changes in the environment and health
  • Enable surveillance of the status or trends of public health events associated with environmental exposures
  • Provide information to decision-makers in order to identify needs and actions both in the environment and in health
  • Provide objective baseline information for developing targets
  • Demonstrate spatial and temporal variations
  • Monitoring effectiveness of policy actions
  • Promote specific policy issues

Between 2001 and 2008 ESR was commissioned by the Ministry of Health to develop a functional core set of environmental health indicators for New Zealand.

More recent EHI data and reports can be found on the ESR HAIFA project website and the Massey University EHINZ website.
