Local council representatives are meeting to discuss the hot issue of water management.
Local Government New Zealand is holding its first Freshwater Symposium in Wellington from Monday.
The meeting comes as residents in many towns and cities question water quality and also access to water for bottling plants.
LGNZ President Lawrence Yule, the Mayor of Hastings District Council, says the symposium will seek to discuss many of the major issues around freshwater for New Zealand, local government and its communities.
An outbreak of gastroenteritis in Havelock North in August 2016 shook public confidence in the water supply to the Hawke's Bay town. Some 5500 of the town's 14,000 residents were estimated to have become ill with campylobacteriosis.
Some 45 were subsequently hospitalised. It is possible that the outbreak contributed to three deaths, and an unknown number of residents continue to suffer health complications.
The outbreak was traced to contamination of the drinking water supplied by two bores.
