Southern authorities are warning motorists to take care today as swollen rivers peak in Southland.
The rain has stopped in the headwaters, but peak flows will still be moving downstream today.
The flooding - the second event in nine days - was caused by rainfall of up to 200mm in Fiordland and 40-90mm across all Southland River catchments over about 18 hours on Wednesday and early yesterday morning.
Gore was the only urban area affected. Gore Volunteer Fire Brigade members arrived just in time at two properties to start pumps to stop water from entering houses, brigade chief Steve Lee said.
In rural areas, farmers "knew what to do" and moved stock to higher ground, Environment Southland duty flood warning officer Chris Jenkins said yesterday.
