Fifteen people have been rescued by helicopter from floodwaters on the West Coast.
Buller Emergency Management says it will continue to remain vigilant and keep a close eye on river levels and rainfall overnight.
The 15 were airlifted from one rural property on Powerhouse Rd this evening when they requested assistance after the swollen Christmas Creek cut off road access.
"They have since been taken by bus to an evacuation centre and are being supported by the welfare team," the management said in a statement.
Controller Al Lawn said he was cautiously optimistic no further evacuations will be required in the district tonight based on the latest information from river engineers and meteorologists.
