Monday is set to bring more rain to parts of the North Island and upper South.
Heavy rain is expected to continue for parts of the North Island and the upper South Island, following surface flooding in Gisborne.
MetService said a low pressure system over the upper North Island will drift westwards on Monday bringing more rain to northern and central New Zealand.
A heavy rain warning was in place for Hawke’s Bay south of Te Pōhue, until midnight on Monday.
MetService said the area could expect 100 to 140 mm of rain, mainly about the ranges with peak rates of 15 to 25 mm in thunderstorms.

The heaviest rain was expected about the inland ranges and the coastal hills and ranges south of Napier.
Heavy rain watches were in place for Gisborne, Bay of Plenty, Wairarapa including the Tararua District and Marlborough east of Awatere Valley.
Thunderstorms were also possible for the areas, excluding Marlborough.
It comes after surface flooding was reported in Gisborne on Sunday due to torrential rain in the afternoon.
”There is still uncertainty with the distribution and intensity of the heaviest rain,” MetService said, and advised people to stay up to date with the latest forecasts.
MetService said the rainfall may reach warning criteria in all areas under watches.
Wet weather would also continue for Northland and Auckland on Monday, with showers expected and the possibility of thunderstorms north of Whangaparāoa.
Waikato was expected to have isolated showers and fine spells on Monday while Taranaki to Wellington would have cloudy weather with occasional showers.
Most of the South Island could expect a fine day, with occasional rain for Dunedin, Nelson, Canterbury and North Otago.
