A tour group riding quad bikes in remote Otago high country did not have permission to be on the land where a crash killed two of the party, the station owner says.
Police have launched an investigation and WorkSafe has been notified after the crash in the Kakanui Range, east of Ranfurly, where two people died at the scene on Saturday afternoon.
Dome Hills Station owner David Douglas said the crash happened on a remote part of his 7500ha station - but he was unaware the group was operating on his land and it had not sought permission.
"They didn't ask permission and we knew nothing about it.
"They were there without our knowledge."
