Queenstown police are searching for a man who dealt a coward's punch to a young man at Ballarat Street Mall this month.
The victim was out with friends when he was knocked unconscious by a punch to the side of the head by an attacker at 2am on July 9.
In a Ten 7 Aotearoa video posted by police, Sergeant Sam Oram said the victim had no interaction with the man before the assault and was lucky to be alive.
The victim had been making his way down the mall, play-fighting with a friend, when the suspect began to follow them.
The suspect then approached the victim from the side and punched him in the head.
