MetService has issued orange severe weather warnings, with heavy rain predicted for the north-east of the North Island.
Meteorologist Ngaire Wotherspoon told Morning Report that it would be a "wet and windy start, for a more unsettled week".
A frontal system was moving south-east over Aotearoa today, and this was expected to affect northern and central parts of the country.
It had arrived in Northland overnight, and was spreading downwards through Auckland at dawn, Wotherspoon said.
An orange heavy rain warning is in place for the Coromandel Peninsula from 8am to 10pm on Monday.
Up to 100mm of rain was predicted, and MetService warned that streams and rivers may rise rapidly, with surface flooding, slips and difficult driving conditions.
"Definitely keep an eye out if you're heading out on the roads," Wotherspoon said.
The Bay of Plenty west of Kawerau should also brace for heavy rain from noon until 4am on Tuesday, after the MetService issued an orange rain warning there, with up to 110mm of rain inland and up to 80mm on the coast.

Meanwhile, it was a frosty start for many in the South Island this morning, with some areas dipping to freezing temperatures.
The coldest place overnight was Alexandra, dropping to minus 5.9 degrees.
Invercargill and Queenstown were both sitting on minus 3 degrees.
For the rest of the week, some weaker frontal systems would be moving across the country, bringing more rain and unsettled weather, Wotherspoon said.
