The rain events on January 1 and 2 were extreme in parts of Central Otago and record or near-record rainfall was recorded at several weather stations.
At a council meeting on Wednesday, engineering assistant Alex Peacock said estimated costs to repair water assets as well as emergency response including providing water tankers and portable toilets was $338,400.
Costs claimed to date were $288,264, with an estimated $50,130 of work remaining, Mr Peacock said.
Providing water tankers and Portaloos while there was no supply was required to meet social, economic, environmental and the cultural wellbeing of the community.
Water supplies were not insured and were an essential service, Mr Peacock said.
The council approved $340,000 of overexpenditure to cover these costs.
Emergency roading repairs related to the weather events totalled $725,000.
Damage included scouring and washout of gravelled roads and cycle paths, shoulder and road surface damage to sealed roads and damage to bridges.
Infrastructure services executive manager Julie Muir said 51% of roading repair costs could be funded by the NZ Transport Agency, and an application for $369,750 had been made.
The remaining $355,250 of funding would be sourced from the council’s emergency event reserve which had a current balance of $2.3 million.
