A sprinkler ban has been put in place for Tauranga after the city's water usage peaked last week.
Hot and dry conditions and high demand for water meant that the city's water supply was running thirsty, Tauranga City Council said.
Residents were asked to completely stop using all sprinklers and irrigation systems until further notice.
The city's current water demand was up by 40 per cent on normal average water use.
Average usage during the year was around 41 million litres per day, however, last Monday demand hit 58 million litres per day.
