KEY POINTS:
Heavy rain is expected over much of the country tomorrow, with falls likely to be welcomed along the country's parched eastern coast.
Rainfall was forecast to be heavy across most northern and western districts of both islands, and in the southeast of the South Island, the MetService said.
A rain warning was issued for the North Island south of Waikato, for Nelson, Marlborough and Westland.
The rain warning follows flooding in Palmerston North and Wanganui late last week, when the heaviest rains of the summer hit some areas of the central and lower North Island.
"Some places obviously are going to get heavier than others...and the rain will be similar to what they had then, for some of the time anyway, but it's a much bigger scale event," MetService duty forecaster Oliver Druce said.
"For some areas I would anticipate there will be problems with roads, surface flooding and so on - it's hard to say exactly where, but certainly central North Island, Taranaki, parts of Nelson, the West Coast, the rain will be heavy enough to cause some problems."
Eastern Hawke's Bay, Gisborne, Wairarapa and parts of Marlborough that have been very dry will get some rain, although it would not be heavy, Mr Druce said.
