The fine weather was expected to continue into Thursday and Friday although the Hawke's Bay, the far south and the South Island's West Coast could be in for the odd shower.
But the fine days could come to an end by the weekend with Metservice predicting a front would move over the South Island from the southwest.
It was expected to bring rain to the Western parts of the South Island becoming heavy in Fiordland on Saturday and in Westland, Buller and around the headwaters of the Canterbury and Otago lakes and rivers on Sunday.
While the front was not expected to affect the North Island, patchy drizzle was possible in the Bay of Plenty.
The front would be followed by a change to cooler southwesterlies across the South Island.
