The rain comes after a horrendous weekend of wild weather for parts of Auckland, particularly in and around East Tāmaki, Papatoetoe and Otara.
A tornado ripped through parts of South Auckland on Saturday - so strong that it lifted roofs off, tore through business buildings and sent trampolines flying.
It also ripped up trees and fences; and even sent a shed flying into an ambulance where a pregnant woman was in labour in Otara.
The woman's baby boy still did not have a name as of yesterday, but the couple were thinking of the moniker "Storm" as a fitting tribute to his entry into the world.
Northland to Taranaki, including the Bay of Plenty and the central high country, are all in for showers that will become more frequent this morning and later this afternoon.
And like Auckland, those conditions may turn to heavy rain, thunderstorms and even hail.
Gisborne is one of the better places to be today, as sunny weather is due the whole day.
The only other place in the country to get a near-perfect day is Westport, which is in for a mainly fine Monday - save for the chance of a spot of rain late this morning.
People in around Whanganui, Wellington and the Wairarapa will see a few showers. Those are due to turn into rain later.
In the South Island, MetService has also issued road snowfall warnings for a number of main roads in the South Island.
Lewis Pass (State Highway 7) is expected to get a period of snow showers from about 9am to 2pm today. Up to 2cm of snow may accumulate on the road near the summit - with lesser amounts to 600m.
Snow showers are also due over Arthur's Pass (SH73) from now until about 10am. That area is expected to get anything from about 3cm to 6cm of snow near the summit.
Anyone driving on Porters Pass (SH73) is being told that between 8cm to 15cm of snow may build up near the summit also.
Authorities are due to give an update on road snowfall warnings at 11am.
Scattered rain is forecast for areas including Nelson, Buller and Westland before clearing by this afternoon.
