Flood event
While it was raining in Southland and Fiordland on the morning of 26 January 1984, the rain was forecast to become heavy within 18 hours. Throughout the day the rain got stronger, and after meeting with a southerly front, the streets of Invercargill, Riverton, Bluff, Otautau and Tuatapere started to experience surface flooding at about 9 pm.[2][3][4] The floodwaters continued to rise, to the point where river banks started overflowing, and then houses became flooded. Sandbags and pumping was used to defend against the water, but this did not work well.[3][5]
The Mayor of Invercargill declared a state of emergency the next day, 27 January, at 4 am, due to severe flooding. By this time, entire streets had flooded and people throughout the town evacuated from their homes. The flooding occurred throughout Southland, so the state of emergency was extended to cover it at mid-morning.[4][3] The rain stopped on the same day, but the flooding continued to get worse.[2][3] At one point, Invercargill Airport was three metres deep in water and 10 aeroplanes were partly submerged.[3]
It took until 27 February for the state of emergency to be lifted.[3]
There was 143mm of rainfall in total, which was "almost twice as much" as the month's average. On 26 January, Invercargill had 84.8mm of rain.[3] For the 24 hours before 9am on 27 January, Invercargill Airport had reported 134mm of rain.[6]
The Otepuni Stream and Waihopai River overflowed, which caused the evacuation of about 5,000 people.[7]
Impact
In Invercargill, about 4,000 people were evacuated from 1,000 homes,[7] and it took about a week for them to be able to return. Helicopters rescued a few people from rooftops.[2] Some people had trouble evacuating because they did not want to leave their pets behind.[5] In Otautau, 300 people were evacuated from 190 houses.[7] In Tuatapere, 70 homes were evacuated and 37 were flooded.[7] About 1,200 houses were condemned,[8] and roughly 5,000 tonnes of personal posessions had to be disposed of.[7][2]
There were no human fatalities, although over 12,000 sheep, 334 pigs, 100 cattle and 75 died or were 'lost'.[3][7] In addition, 170 km of fencing and 52 farm bridges were destroyed.[7]
Aftermath
Paid out insurance claims totalled about $55 million.[3] A public flood relief appeal raised NZ$6 million.[7]
In January 2024, Environment Southland has described the event as a 'catalyst' for flood protection upgrades that were later done in the area.[8][9]
