Heavy rain is expected about western parts of the South Island today while the rest of the country is in for a mostly fine day.
However, from tomorrow most areas of the North Island will be wet with rain from a front moving north that is currently hanging over the South Island.
MetService has a heavy rain warning in place for the Westland Ranges from Otira to Franz Josef Glacier, and for Westland from Franz Josef Glacier southwards.
The same warning was also in place for the headwaters of the Otago rivers and lakes and Fiordland north of Doubtful Sound.
Looking ahead, a front over the South Island moving slowly northeast would weaken over the North Island during Monday and Tuesday, bringing rain to most areas of the North Island.
