Two people from Fire and Emergency New Zealand (Fenz) were seen inspecting the scene and what was left of the vehicle at Driftaway Queenstown on Friday afternoon.
A single pump truck and crew from Frankton Fire Brigade arrived at the scene in Lake Ave around 8.50pm on Thursday and had the blaze extinguished in about 20 minutes, a Fenz spokesman said.
The occupants escaped unharmed.
The spokesman said an investigation had been completed but could not confirm its result.
Only part of the lower half of the Mercedes-Benz Sprinter’s body remained. The caravan, which is believed to be hired, was several metres away from all neighbouring campers.
A spokesman for Driftaway Queenstown confirmed the occupants of the rental caravan were safe and staying at a villa at the holiday park in the meantime.
