The local council is investigating the planned use of 10-tonne Unimogs to carry tourists on a Queenstown road described as one of the world's most treacherous drives.
Go Orange plans to transport up to 20 people in each of the Mercedes Benz trucks along Skippers Rd, through the Skippers Canyon, to go whitewater rafting on the Shotover River.
Some worry the 22-kilometre historic road is too narrow for the Unimogs and that they are not suitable to be used on the bridge at Deep Creek. But Go Orange says the Unimogs were selected to replace old buses because of their "capabilities, suitability and safety".
Plans to use 10-tonne Unimogs to transport whitewater rafters on a notorious Queenstown road are on hold because the company is not "fully comfortable" with the trip.
Adventure tourism company Go Orange wants to drive the 20-seater trucks into Skipper's Canyon on the 22-kilometre Skippers Rd, which was hand carved by early goldminers.
The company was not yet using Mercedes Benz Unimogs commercially in Skippers, manager Luke Taylor said.
"We're still in the process of training and evaluation and development of the product."
A bag drop-off and early check-in initiative being trialled by Air New Zealand in Queenstown could be rolled out to other locations if it proves successful, the airline says.
The national carrier says it will introduce a pop-up check-in and bag drop service in downtown Queenstown from November 20.
Passengers on the airline's domestic and international services will be able to use the service on the day of travel as part of a three month trial.
