The Tūroa side of Mt Ruapehu will be closed for the rest of the season.
"After a number of hopeful assessments, a decision has been made today to close Tūroa for the 2022 season," a post on the Mt Ruapehu Facebook page said.
"The damage is just too extensive, and rebuilding is not a possibility."
The post said it had been "one hell of a season" for the crew.
"They have sought out the impossible and made the best of what they were given. We know some epic riding was had, albeit over fewer days than we had hoped."
