Akaroa residents will only be able to water their gardens on certain days as a forecast hot summer is expected to drain the town's stream-fed water supply.
The restrictions mean residents whose street address is an odd number can water their gardens on odd numbered days, and even numbered addresses on even numbered days.
Summer was predicted to be hot and dry so demand for water was expected to be high, Christchurch City Council's water manager Tim Joyce said.
Residents and holidaymakers needed to be responsible and conserve water to prevent further restrictions.
