Wind and rain look set to dampen New Year festivities over many parts of the country.
WeatherWatch.co.nz head analyst Philip Duncan said the same weather pattern which contributed to a cloudy and damp Christmas Eve in some areas looked likely to return in the final days of 2012.
This meant a higher risk of wind and rain on New Year's Eve and campers are being warned to keep up to date with weather forecasts and potential warnings.
A similar weather set-up as during Christmas - highs either side of New Zealand but not directly over the country - looked likely for the final day of the year, Mr Duncan said.
"Just like for the start of Christmas we expect a high to the east and another one in the Tasman Sea, lowering the air pressure here at home and increasing the risks of wind and showers."
The weather forecast showed wet weather clearing during New Year's Eve over the North Island and rain moving up the West Coast of the South Island.
Gusty northwesterlies were predicted for central New Zealand, including Wellington.
However, despite the potential change in weather, most main centres still looked fairly dry at this early stage, Mr Duncan said.
"Don't go cancelling any plans just yet."
Auckland has a 30 percent chance of showers with westerlies picking up. New Year's Day could be windy but dry and cloudy.
Wellington is expected to be dry with near gale northerly or northwesterly winds on New Year's Eve - with New Year's Day looking similar but possibly showery.
Christchurch is forecast to be dry and warm, but perhaps cooler, cloudier and windier on January 1.
Dunedin can expect sun interspersed with few showers and northwesterlies.
Mr Duncan said he had been using the same models that picked Cyclone Evan's path two weeks in advance.
"I tend to be a glass-half-full kinda guy and while the forecast may not be ideal, keep in mind long-range predictions are just a basic guide for the weather pattern.
"We are seeing another unsettled spell of weather, but it may be more like a hot spring weather pattern than the tropical summer system we've just had."
The wild weather may be be short-lived, a forecast high moving in to settle things down for the start of January.
