“Watercare technicians are on site to rectify the issue.”
Watercare head of water Sharon Danks said about 7.45pm water was able to flow through the pipes again.
“Water should be restored to all customers by about 10pm,” she told the Herald.
“Our crews will continue to work on the broken section of water main overnight and are not expecting further impact to customers.
“We’d like to thank our customers for their patience while we’ve worked to restore water services and get repairs under way.”
Earlier, local councillor Richard Hills said Watercare informed him the burst was “complex”.
“It’s on a main transmission line, so the disruption to the network is wider than usual on a break like this,” he wrote on Facebook.
“The Watercare team are arranging for water tankers planned to be stationed at 22 Potter Ave and 46 Raleigh Rd, however I’m not sure of the timeframe for them being onsite at this point.
“Please check in on neighbours and friends who may need drinking water if you are able to give them assistance.”

A Northcote movie theatre, Bridgeway Cinema, said it had to make the decision to cancel sessions tonight because of the water issue.
“Unfortunately, we have had to close tonight due to a burst water main in Northcote, which has affected the water in the whole area,” it posted.
“Due to health and safety risks, we are cancelling all further sessions tonight.”
