Chemical Injuries Surveillance

Sunday 28th May 2023

Between 2001 and 2009, ESR was commissioned by the New Zealand Ministry of Health to develop and maintain a national Chemical Injury Surveillance System (CISS). 

The system involved the collection and analysis of hazardous substance injury data including

  • mortality data
  • inpatient hospitalisation data
  • poisoning events from selected hospitals
  • chemical/poison related notifiable injuries 
  • summarised National Poison Centre calls
  • Public Health Unit spraydrift complaints

Chemical injuries reports for 2001 to 2008 are available here.

For more recent chemical injury data please phone 0800 588 265 or e-mail Massey University
