Much of the country is due for another wet day on Tuesday, with a chance of thunderstorms for many areas, and a possibility of overnight snow on the Desert Road.

Early on Tuesday there were no forecasts for any more tornados, after tornados damaged buildings in New Plymouth and Ohope on Monday evening.

A building at the Ohope Top 10 Holiday Park in Whakatane suffered serious damage as the tornado struck, reported Newshub.

Ohope Beach Top 10 Holiday park manager Mark Inman says a building at the camp had been "completely blown apart" by the rapidly rotating column of air.

MetService meteorologist Bill Singh says overnight much of the country had consistent showers and there were some heavy falls but no more tornados were reported.

In the 12 hours to 5am Tuesday, 48mkm of rain was recorded in the ranges of Bay of Plenty east of Whakatāne, and there was 42mm in the Wellington suburb of Karori.

During the 24 hours to 5am, the wettest place in the country was Mt Taranaki, which had about 150mm, while Takaka had about 94mm.

"There's a very unstable and very complex low, a broad low, circulating around the whole country.

"With the instability there's going to be a lot of showers, with some heavy falls and thunderstorms. That's going to affect the country for the next few days."

There was also a chance of snow on the Desert Road overnight Tuesday.

MetService expects the west of the North Island and the top of the South Island to have the wettest weather on Tuesday, with some heavy falls, some with hail, and possible thunderstorms.

Gisborne and Hawke's Bay could escape with just a few afternoon showers, while Canterbury and much of Otago could have a dry day, although some showers are possible about the Canterbury foothills.

By Friday, snow could be down to 500 metres in the south of the South Island, MetService said.
