A Wellington man in Auckland for his stag party is recovering in hospital after he was seriously injured during a fight involving up to 20 people in the CBD.
Leighton Roberts was celebrating his upcoming wedding to fiancee Brooke Anderson when he was king hit.
His brother Brad Roberts told Fairfax that the 28-year-old was hit three times in the back of the head when he intervened to stop his cousin being attacked by "two random men".
Leighton Roberts was hit and fell to the ground on Fort St at just before 10.30pm on Saturday night.
Police are now investigating the assault but say they have no leads on who injured the stag.
