Most other regions will be dry but some rain is possible briefly in Southland and Otago and a few light showers may also hug Coromandel Peninsula to the east and Bay of Plenty.
Winds are forecast to be light in the North Island with a westerly flow over the South Island.
On Easter Sunday a bit of cloud and a few light showers are expected in the western side of both islands, mostly the West Coast and the southwest corner of the North Island. However, it should be mostly dry, with light winds.
On Easter Monday, rain retuns to the West Coast with heavy falls. A few showers may affect the North Island's western side but most other places will be dry with fairly light winds.
After a fairly unsettled weekend, with showers over much of the country, today is looking "much more stable", MetService meteorologist Arno Dyason said.
The Black Caps will be pleased the rain that has plagued the past two days of their test match against England at Eden Park in Auckland will be mostly gone today.
The forecast is for a mostly fine day, with just a few isolated afternoon showers and a high of 24C, giving them the best chance to seal a famous win.
Ed Sheeran concert-goers bound for the pop star's last Auckland show at Mt Smart Stadium tonight are also in for a much drier time than those who attended Saturday's show.
"Showers and thunderstorms that were in northern areas have all eased," Dyason said.
From Saturday evening to yesterday morning more than 100mm of rain fell in parts of the Gisborne ranges.
Today, most areas from Northland through Auckland the Bay of Plenty and across to Gisborne, which received a lot of rain over the weekend, are in for a mostly fine day with just a few showers forecast.
"Elsewhere in the North Island is in for a really fine day. In Wellington the biggest issue will be strengthening northerlies."
The South Island will also be getting a great start to the week, with only a few showers forecast on the West Coast and some spots of rain in the far south.
Tomorrow a front will start to move up the South Island, briefly bringing heavy rain to the West Coast, but warm northwesterlies to the East Coast.
Christchurch is forecast to reach 28C tomorrow.
The North Island should improve further into Tuesday, until the front arrives in central areas on Wednesday.
"However, the front will weaken as it moves north and there should only be a few showers with it."
On Thursday it drifts further north to Auckland, bringing the odd shower.
A tropical low forming near Fiji later this week may develop into a tropical cyclone.
Dyason said at this stage it was really low risk but they would know more about its chances of becoming a cyclone later this week.
As the storm was in Fiji's area, it was up to the Fiji Metservice to make the call on if it would develop into a cyclone.
WeatherWatch NZ said the system, which would be called Cyclone Jo, could hit Fiji and Tonga next Monday.
However, WeatherWatch analyst Philip Duncan also said it was too early to confirm its exact path.
In the meantime there were three tropical storms messing with Australia this week.
The first cyclone, Cyclone Marcus, struck Darwin last week before tracking over the Indian Ocean. It has been downgraded to a storm bringing wind and showers into Perth and across South Australia today.
Cyclone Nora is bringing rain in northern Australia, while Cyclone Iris was sitting between Australia and Fiji and there was uncertainty if it would hit either country.
