The last few days of 2013 are likely to bring showers, some heavy, to most parts of the country, MetService says.
An area of low pressure off the East Coast would bring a "fair bit of wet weather" to Canterbury, Otago, the Wairarapa and possibly Auckland over the next day or two, MetService duty forecaster John Law said.
Escaping the rain today and tomorrow was the West Coast, which had a "decent couple of days" in store, Law said.
Heading through to the weekend, another system was set to move in from the northwest.
"That could bring with it a fair bit of cloudy and wet weather up towards the northern parts of New Zealand," he said.
The Far North could also expect some heavier falls, so it was "definitely something to keep an eye on as we head towards the weekend and even the start of next week".
A severe weather outlook showed there was a moderate risk of heavy rain for the Bay of Plenty and Coromandel on Sunday.
"Warm, moist air is just going to feed in there and funnel in towards the guys in the Bay of Plenty," Law said.
"As we head through towards the start of next week we'll find this whole system pulls away and we'll have showers come across, and a bit of a change."
