Police say they are frustrated at the behaviour of Queenstown's winter revellers after almost 30 incidents - most involving alcohol - at the weekend.
More than a dozen arrests were made between Friday night and late yesterday, police said.
Many of the revellers were celebrating the start of the Queenstown Winter Festival.
But festival organisers were quick to point out none of the arrests was believed to have occurred inside organised festival events.
Senior Sergeant Keith Newell said Saturday night, in particular, was "hectic".
