Many parts of New Zealand will need to brace for heavy rain over the coming days.

Coromandel and Bay of Plenty were drenched overnight, but the worst looks yet to come.
A MetService heavy rain warning is in place for Bay of Plenty from 3pm on Monday until 11am on Tuesday with up to 180mm of rain expected to fall inland and up to 100mm on the coast.
MetService forecaster Heath Gullery said the heavy rain could lead to flooding, slips and disruptions to travel.
"This is tracking down from the subtropics so kind of from the Coral Sea tropical region, that’s why it’s going to bring some very warm humid air onto the country, even more so than we’ve seen with the last week."
He said north and east of the South Island plus parts of the North Island will be hit be the rain late Tuesday and Wednesday.
A heavy rain warning is in place for Nelson and west of Motueka until 10am on Tuesday with up to 150mm of rain expected to fall.
