None of the six people involved in the incidents was seriously injured.
A female tourist was airlifted to Dunedin Hospital with "moderate" injuries after the Toyota Rav4 she was in flipped as it careered off State Highway 8 between Tarras and Cromwell, near Bendigo, at 2.20pm.
A St John spokeswoman was unsure what injuries the patient suffered but confirmed they were not life-threatening.
The three others in the vehicle were taken to Cromwell Medical Centre by ambulance.
Sergeant Bruce Terry, of Cromwell, said it appeared the driver had tried to correct the vehicle after it drifted slightly left off the road and then lost control.
It flipped several times before coming to a stop on its side, on a wire fence. Some of the occupants were able to free themselves and helped the others out of the wreck.
Sgt Terry praised the "fantastic" actions of the members of the public who stopped to help the injured tourists before emergency services arrived.
There were slight delays for motorists while police examined the crash site.
Sgt Terry said it was too early to know whether the driver would be charged.
At 3.30pm, 30km away at Champagne Gully, north of Clyde, there was another near tragedy when a Nissan Navara ute rear-ended a Mazda car that was stopping behind two others waiting to turn right off State Highway 8.
The crumpled Mazda ended up in a field after rolling off the road.
The two solo drivers of the vehicles involved walked away from the wreckage and were assessed by ambulance staff. No further treatment was needed.
Senior Sergeant Ian Kerrisk told the ODT criminal charges were likely. The crashes prompted police to warn motorists in the Cromwell and Omarama areas to take care driving in the high winds.
"Police are aware of a number of minor incidents in the area due to the winds and want to remind people travelling on the roads in the Central Otago area to drive to the conditions," a spokeswoman said.
