Northwesterlies are expected to bring the temperature up, but are also forecast to bring heavy rain to Fiordland and Westland.
"There is a bit of spill over for the likes of Southland and Central Otago, but only a few showers.
"Most places will remain pretty good for Saturday. If we were to take Saturday as a whole then the North Island is looking relatively good with a few isolated showers around, but most places are generally fine.
"It is the same for the top of the South Island around those eastern areas, but as our front moves up the South Island will see cloud increasing into the evening on Saturday."
On Sunday, the front will be sitting close to Wellington and the capital will get a period of rain and blustery strong winds.
"By the end of the day, the front will get slower and weaken, so by the end of Sunday it will still not have reached Auckland, it will still be around Taranaki, the Wairarapa, and just reaching Palmerston North" Murray said.
"Auckland, Coromandel and the Gisborne areas will be not too bad for much of Easter, but their day which will be not so great will be Monday as that front moves over, bringing cloud and some showers."
Murray said the weather will be quite changeable, so it is best people check the forecast, especially before people head away on holidays and camping.
"Temperaturewise it can be quite a contrast, so the day time temperatures can be 20C but overnight you get down quite low, so it is important that people are aware and prepared."
