A man was taken to hospital with head injuries after an altercation between two groups on a suburban street in Papamoa.
Police say a hammer and a vacuum cleaner pipe were used as weapons during the confrontation, about midday yesterday.
Tauranga police Senior Sergeant Cam Anderson said one group carrying weapons attacked the other group at a Dickson Rd property before fleeing the scene.
St John district operations manager Jeremy Gooders said a man in his 20s was taken to hospital with moderate head and arm injuries after the assault.
Mr Gooders said by the time ambulance staff arrived the altercation was over and the victim was standing on the street with the police.
