Aucklanders should brace for another wet weekend and Civil Defence warns it could cause more disruption.

Rainfall is expected to become widespread on Sunday and Monday. Heavy falls were possible in some areas, MetService said.

That had the potential to create problems in areas badly affected by storms and flooding earlier this month, including the Hunua Ranges, Clevedon, Kawakawa Bay and west Auckland.

Craig Glover from Auckland Civil Defence said people should to keep a close eye on the weather forecast, especially if they lived, worked or travelled in flood-prone areas.

"It's not looking like the same kind of weather that we have experienced over the last couple of weeks, but, given some of the quite significant rainfall that we have experienced, we just want to be prudent and just make sure that we are as prepared as we can be," he said.

People should clear drains and debris on their properties to prevent more damage, Mr Glover said.

Teams were out clearing slips and other debris that came down in the last storm.

Watercare warned this week that further heavy rain could wash more silt into Auckland's water supply dams.

Drone footage revealed the extent of the slips and erosion around the Hunua Ranges.

Watercare said the nature of the storm and the damage it caused was unprecedented.
