Aucklanders have cut their water use by millions of litres after storms two weeks ago flushed silt into a water treatment station.
Yesterday, consumption was 397 million litres, below the Watercare target of 400 million litres or less.
Auckland's average use is 450 million litres a day.
Water advice line advisor Olivia Tukuogo said reducing water was easy.
"Take a shorter shower - also a great way to save on your energy bill - and catch the cold water in a bucket while waiting for the heated water. This water can be used to help fill your washing machine, or the toilet cistern.
"Wait until you have a full load before doing the laundry or the dishes. Rinse using a bowl in the sink or pop the plug in rather than leaving a tap running. Recycle water from drink bottles and dehumidifiers over the garden."

The Ardmore treatment plant, which supplies about two-thirds of the city's water supply, was swamped with silt after last week's devastating downpours.
