Aside from Eketahuna, a total hosing ban is in effect for all towns in the Tararua District.
A Tararua District Council spokesperson said a total hosing ban meant garden sprinklers, unattended water systems, soak hoses and hand-held hoses cannot be used.
The ban also means no cleaning cars, washing houses or windows and no refilling of swimming pools. The use of buckets is permitted.
The council draws water from local rivers to fill the town water supplies.
The spokesperson said the amount of water the council was permitted to take from rivers changes based on how high or low river levels were and was prescribed by Horizons Regional Council.
