Maintenance shutdowns, restrictions and notices

Boil water notices

Council issues boil water notices and precautionary boil water notices when a Council-supplied water source poses a risk to the safety of the community. During a boil water notice, people connected to the particular water supply must boil their drinking water and water used in food preparation and for hygiene purposes for at least one minute before consuming.

Current boil water notices are in place for:
Montalto ​​- permanent boil water notice

Current restrictions

Council uses water restrictions during the summer months or during emergencies to make sure that water is available to everyone and that supplies are made to last. We are also expected by our resource consents to take care with our use of water.​​

The following restrictions are in place as of 29 January 2024 and are explained below:
