As the Minister for Emergency Management and Recovery visits Wairoa today, a mayoral relief fund on Givealittle for the town has swelled to more than $120,000.
Minister Mark Mitchell had already announced the government would contribute $300,000 to help communities in Hastings, Wairoa and Tai Rāwhiti.
The town's mayor Craig Little has warned the cost of last week's floods could be more than $40 million, which he says the town can't afford.
Some 500 homes were damaged and many families have been left homeless.
Craig Little is set to hold a media briefing with the Minister later this morning.
