Sergeant Steve Watt, of Queenstown, said the burglary occurred some time between September 24 and October 15.
Each of the black doors, about 4.8m long, weighed about 900kg.
"They definitely would have needed a vehicle to transport those and more than likely lift them."
Police are also investigating historic damage done to three camper vans parked at Frankton.
Sgt Watt said vans had been parked in a rental vehicle car storage area on Hawthorne Dr, opposite Wakatipu High School, and broken in to sometime between November 25 and October 2.
"Once inside they've let off fire extinguishers, broken shower doors [and] smashed GPS units."
• A 21-year-old male was given a pre-charge warning by police after he was found in possession of 1g of cannabis and a "large bong".
Sgt Watt said police noticed a "smell of cannabis" coming from the vehicle he was in on Kawarau Rd about 2am yesterday, so searched it.
The male also underwent a compulsory impairment test which he "satisfactorily completed".
