An Australian man's night on the town ended with him being escorted from a Queenstown hotel in a dressing gown after he crashed out naked in the wrong room.

A woman hid in her hotel bathroom after the drunk 29-year-old wandered into her and her husband's room and fell asleep on their bed on Saturday morning.

Sergeant Steve Watt, of Queenstown police, said the man was escorted home in a dressing gown after being woken by the hotel concierge.

"He was a bit surprised that there were two people in his room and he was butt naked," Mr Watt told the Southland Times.

The man told police he been brought back to the hotel from town by a woman but at some point wandered out of her room into the hallway stark naked.

He then wandered into another room, occupied by a husband and wife, and had curled up and gone to sleep, he said.

The couple called the hotel reception, with the wife hiding in the bathroom waiting for staff to arrive.

The man was not charged, Mr Watt said. "It was far too funny."
