The red heavy rain alert issued for North Otago, Dunedin and coastal Clutha is not due to expire until 9pm Friday.

Another 70 to 100 millimetres is forecast to fall, meaning the region will have received more than two months' worth of rain over three days.

Overnight, a state of emergency was declared in Dunedin, and evacuation centres were opened for residents whose homes were threatened by flooding.

At least 18 roads were closed across the city due to flooding and slips, with further closures announced in Clutha District.
