Police took a drone being flown by a Chinese visitor at Fox Glacier on Monday.
Senior Constable Paul Gurney, of Haast police, said the drone was spotted by helicopter operators, flying over a hangar and aircraft on the ground.
Concerned staff followed the drone and located the operator at a nearby motel. Police were called and seized the machine.
A Chinese man (73) was officially warned for operating an unmanned drone in a manner which caused unnecessary danger to aircraft.
''Efforts are being made to step up information and warnings to visiting tourists about where they can fly drones in Fox Glacier,'' Snr Const Gurney said.
Police advise that anyone spotting drones near airports or aircraft bases should ring 111.
