The North Island will see showery conditions tomorrow while the South Island will have fine conditions.
The showery conditions over the North Island will clear by Tuesday, which will turn into a fine day.
“Another cold front is then expected to move slowly north over the South Island on Tuesday, Wednesday and Thursday, bringing rain to many South Island areas,” Owen said.
“There is a risk of heavy rain for western parts of the South Island during this time.”
Meanwhile, an intense subtropical low is expected to move southeast towards Aotearoa on Friday.
“At this stage, this is expected to bring heavy rain and severe gales to many North Island areas,” Owen said.
The severe weather outlook is for a moderate risk of heavy rain and severe gales in Tairāwhiti/Gisborne, the Bay of Plenty, Rotorua, Coromandel, Auckland and Northland.
“As this is still several days out, there is still uncertainty as to where the worst of the rain and gales will be, so people are encouraged to keep up to date with the latest forecasts since the heavy rain and strong winds could bring significant impacts,” she said.
