A St John ambulance spokeswoman said a child had been seriously hurt and three adults moderately injured in the incident on Ski Field Access Rd about 5pm. She said two helicopters and three ambulances had been sent to the scene.
But police say five people, including a 4-year-old, have minor injuries and the child was taken to hospital by chopper as a precaution.
The area had snowfall today and a police spokeswoman said the roads were slippery.
The bus was carrying 32 passengers when it crashed into a ditch about 1m off the road. No one was trapped in the vehicle.
Police are making inquiries into the cause of the crash.
The St John ambulance spokeswoman earlier told the Herald the injured child would likely be flown to Dunedin Hospital and the adults would be taken to Queenstown Hospital.
The Remarkables ski area manager Ross Lawerence said the crash happened about 8.5km up the road from the State Highway 6.
"[The bus] left the road on the left-hand side and went into the watercourse."
All vehicles using the road today had to use chains, he said.
Lawerence told the Herald the bus involved was a charter and the people on board had been skiing today.
He was unable to confirm whether the passengers were tourists or locals.
