Soaring temperatures and rapidly dropping river flows throughout the district have forced Tararua District Council to impose water restrictions.
"River flows have dropped dramatically over the past couple of weeks and this has reduced our daily water takes for towns, so it's essential we conserve water as we head towards a very dry period," council spokesman Dave Watson said.
Showers predicted by the MetService in early December never arrived and the district has sizzled with temperatures reaching 30C on some days, leaving gardens and pastures parched.
This has forced the council to put a total hosing ban in place in Norsewood, while water restrictions apply throughout the rest of the Tararua, with soak hoses banned.
Water restrictions in Dannevirke mean homeowners can only water their gardens, using hand-held hoses, on alternate days.
