Workers and school students face a wet commute around much of the country this morning.
And the rain and showers will persist in most areas as a front which dumped heavy rain on parts of Westland overnight sweeps over the North Island today.
In Auckland, rain and showers set in from soon after 5am and some heavy, possibly thundery, downpours are expected this afternoon.
The West Coast glaciers region, damaged by last week's flooding, was doused with a further 150mm of rain in the 24 hours to 7.30am and the Hokitika area received nearly 40mm, said MetService meteorologist April Clark.
"The worst is over for the West Coast. We have a heavy rain warning still in force for northwest Nelson."
