Rain had already begun to fall across much of the east coast of the North Island, Wellington, and most of the South Island, while gale force winds were blustering through the Central Plateau upwards.
Conditions were only expected to worsen in some parts tomorrow as MetService was predicting cloud to increase throughout the North Island and late rain to develop from Waikato and Bay of Plenty southwards.
In the South Island, heavy rainfall could be expected in the west coast, and scattered rain further east.
MetService forecasters said northwesterlies could rise to severe gale in central areas, but a severe wind warning for Tararua District and Central Hawke's Bay was lifted this morning.
The New Zealand Transport Agency was warning motorists to drive to the conditions, due to the weather being bad across most of the country.
Wellington Operations Manager Mark Owen said drivers should "exercise great care".
"We're asking motorists to allow extra time and take care this Labour Weekend when heading out on the highways, and to make the most of their journeys rather than rush them."
