Two helicopters and two fire trucks with tankers are tackling a burning car that's blocked off the Remarkables Ski field access road near Queenstown.
NZ Ski says just before 1.30pm a vehicle travelling down the access road experienced mechanical issues and caught alight.
One witness reported the four-wheel-drive caught fire, before exploding and rolling downhill.
Witness Sean Parnell said the occupants of the vehicle "managed to grab some of their gear and run beforehand."
No injuries have been reported.
