Overview

On 12 September 2016, the Government announced that an Inquiry into the Havelock North water supply contamination incident would be held.

The Inquiry members appointed are Hon Lyn Stevens QC (chair), Dr Karen Poutasi CNZM and Anthony Wilson ED*.

The Inquiry follows the widespread outbreak of gastroenteritis in Havelock North in August 2016, with more than 5000 people falling ill, following the confirmation of the presence of E. coli in the water supply.  Testing through the health system led the Hastings District Council and the Hawke's Bay District Health Board staff to suspect that Campylobacter as the primary infectious agent.

Drinking water supplies across New Zealand rely on different methods of take and treatment, depending on the nature and security of the water source.  Drinking water supplies are regulated under the Health Act 1956 and the source of drinking water is regulated under the Resource Management Act and National Environmental Standards for sources of drinking water.  The National Environmental Standards are given effect to by the Hawke’s Bay Regional Council. 

New Zealanders expect that water reticulated to their homes and businesses for drinking purposes will be safe to consume and use. The Havelock North water contamination incident has risked damaging public confidence in local drinking water supplies.

The Inquiry will report back by 31 March 2017 and will focus on:

  • how the Havelock North water supply system became contaminated
  • how this was subsequently addressed
  • how local and central government agencies responded to the public health outbreak that occurred as a result of the contamination
  • how to reduce the risk of outbreaks of this nature recurring.

It will also consider any necessary changes to prevent or minimise similar incidents in the future.

It is expected that the Inquiry will conduct an initial public hearing in the Hawke’s Bay in the coming weeks.
