Watercare says August will have to be twice as wet as usual if Auckland's water supplies are to get back to a normal level.
A record dry start to the year means the city's four main dams in the Hunua Ranges are only about two thirds full - they should be at 90 percent at this time of the year.
At the start of July Watercare called for people to use less water, suggesting showers be limited to four minutes.
But are Aucklanders heeding that call? Reporter Chen Liu went to find out.
