A lack of rain and high demand has resulted in water restrictions being introduced across the South Taranaki district.
They come into effect on Saturday, March 12.
All unattended hoses, sprinklers and irrigation systems are banned, and hand-held hoses may only be used early in the morning or in the evening on the "odds and evens" system.
That means at even-numbered houses on even calendar dates and at odd-numbered houses on odd calendar dates.
South Taranaki District Council group manager of community and infrastructure services Fiona Aitken said water supplies in Ōpunakē, Manaia, Rāhotu, Waverley and Pātea were low.
