The deluge that drowned crops, dug up roads, and overwhelmed water supplies in Otago to start the year was a "real kick in the teeth" for many, a local official said.
In some places, localised downpours dumped up to a third of the annual average rainfall for an area onto land and into rivers that could not cope.
The region's mayors said Otago had weathered a major storm, as a clean-up got underway yesterday.
Central Otago Mayor Tim Cadogan said things were slowly returning to normal but roads remained closed, bridges were damaged, and three towns were on boil-water notices.
Clyde residents told Cadogan they'd never seen rain like the weekend's downpour.
Farmers in the Maniototo and around Alexandra said during the downpour their farms received a quarter to a third of their annual rainfall in the first three days of the year.
"That's a major weather event that you can't over-build your infrastructure to plan for," Cadogan said. "You can't really prepare for that scale of flooding.
"It's a real kick in the teeth at the start of the year that everybody had great hopes for, but we're resilient people."
Patearoa and Naseby had boil-water notices issued at the weekend, and the Central Otago District Council issued one for Ranfurly as well yesterday.
Elsewhere in Otago, Snow Avenue, in Middlemarch, was inundated with rain and looked more like a river than a road during flooding on Saturday.
After the water receded, on Sunday, an intense cloudburst reflooded buildings in the area and a lightning strike briefly cut the town's power.
Residents were advised not to flush toilets for two hours and residents were advised yesterday not to drink water from bores unless they treated the water with a filter, as it was probably contaminated.
Dunedin Mayor Aaron Hawkins said once the clean-up was done, the council needed to help Middlemarch businesses recover the same way the council would if the businesses were in George Street or King Edward Street in Dunedin.
Hawkins said the council would meet the community as soon as possible to talk about economic development support for the Strath Taieri.
The council would also investigate what could be done in future to mitigate heavy rain flooding events.
A lot of work had already been done in the Waitaki in recent years to cope with floods, Waitaki Mayor Gary Kircher said.
But with a large district and variable weather, Kircher said the district could never be "bullet-proof" against floods.
The challenge was to predict what would happen and where, and ensure any damage could be fixed as quickly and cost-effectively as possible, he said.
