Taranaki and the Tararua Range will also see heavy rain from midnight Thursday to Friday afternoon.
The front, preceded by a strong moist northerly flow, will move north today and across the North Island tomorrow bringing periods of heavy rain and thunder with it.
Metservice meteorologist Angus Hines said some spots will have “quite heavy” rain as the band of rain moves up on Friday but it’s not all bad news.
“It’s actually going to ease up nationwide – much of the country looks like it will have quite a clear weekend for Friday afternoon, and for the North Island that will last all the way until Sunday”.
However, for the South Island the rain will settle back in on Sunday – and before either Island gets that respite, Hines said there was “a fair amount of rain to get through first”.
