Police from Timaru and Pleasant Point were called to assist Waimate officers after a large brawl broke out in the town.
Constable Paul Alden said police, St John and the Waimate Volunteer Fire Brigade were called to High St just before 3am on Sunday, after two men were assaulted and a ute was driven on a footpath through crowds of people.
''One gentleman has been assaulted with a weapon ... receiving head and arm injuries,'' Const Alden said.
The other man was assaulted in similar circumstances, about 50m from the scene of the first assault.
Both men, whose ages were not known, were taken to Timaru Hospital and discharged later on Sunday.
The weapons involved were unknown.
Const Alden said some of the people involved in the altercations then got into a white ute, which then allegedly mounted a kerb and was driven at a crowd of people on a footpath.
Police are not aware of anyone being hit by the ute.
Investigations continued into how the altercation, involving about 30 to 40 people, started. No arrests had been made, but charges were pending, Const Alden said.
Police were still taking witness statements.
''The investigation is in its infancy. We've got a heck of a lot of work to wade through,'' he said.
''We're starting to paint a picture of what's actually happened, but we've got a few other bases that we've got to cover first.''
Anyone with more information about the ute or the altercation should call Waimate police on (03) 689-7272.
