A wet weekend is ahead with a low over the Tasman sea bringing unsettled weather until early next week, MetService says.
Spokesman Daniel Corbett said the weather system was expected to deliver several bouts of wet weather during the next few days.
"On the weather map, it looks a bit like a bicycle wheel with spokes rotating around the centre.''
Northland, Bay of Plenty, Waikato and Nelson are currently covered by either a severe weather warning or watch for heavy rain in the next 24 hours or so, Mr Corbett said.
"After that it remains unsettled, particularly in the north and west of both islands.''
