He asked people to avoid washing cars and turn off auto-irrigation systems.
Watercare also praised efforts by commercial customers for water savings including petrol stations that had temporarily switched of car washes.
"We welcome Z and Caltex closing their commercial car washes across Auckland in an effort to reduce water use and encourage other businesses to follow their lead," said Jaduram.
Yesterday Auckland University was found defying the water savings by running sprinklers over the weekend.
Auckland Council's development arm Panuku also ran sprinklers in Wynyard Quarter on Saturday.
On Friday, Watercare urged the public to stop watering gardens, washing their cars and to have shorter showers after storm damage to the Ardmore treatment plant meant it was treating 50 per cent less water than usual.
The council now has all sprinklers and fountains switched off and Auckland Transport has also ordered that waterblasting at its bus shelters, train stations and platforms only be done if absolutely necessary.
Initially the region met the savings target but since the start of the working week has failed on consecutive days.
