A new report says the cost of river flooding to property values is already topping $100 million per year and it's predicted to skyrocket even further.
According to CoreLogic data, Otago's property values would be the hardest hit in the future - accounting for 15 percent of the national average river flooding property value loss.

CoreLogic head of research Nick Goodall spoke to AM about the report.
