The upper North Island is expected to get some downpours over the next 24 hours, as MetService issues a severe weather warning for Northland.
MetService is expecting to see around 120mm of rain fall in the eastern hills over Thursday night and Friday, while around 60-90mm could fall elsewhere in the area.
A heavy rain warning was issued for Thursday night, which warned that streams and rivers could rise rapidly, while flooding and slips were also possible during the wet weather.
The weather warnings came after a humid northeast flow over the upper North Island was expected to spread south - which could see Auckland, Coromandel Peninsula and northern Gisborne get a heavy downpour as well.
It comes a week after the remnants of tropical Cyclone Fehi barrelled down the country, leaving a trail of damage to roads and buildings in its path.
Friday's weather warning is in place until 3pm.
MetService is urging people to keep up to date with the latest forecasts in case conditions change.
