A brawl at the Bridge Tavern at Millers Flat on Saturday night resulted in the arrest of a Roxburgh man.
Sergeant Ian Kerrisk, of Alexandra, said three police officers attended the incident and initial reports were that up to 20 people were involved.
The brawl involved two groups, one from Roxburgh and the other from out of town.
Several weapons were presented, including wooden batons.
"The people involved were less than co-operative regarding what had happened," Sgt Kerrisk said.
A 22-year-old Roxburgh man had been charged with possessing an offensive weapon - a wooden baton - and further arrests were likely, he said.
The man will appear in the Alexandra District Court on Wednesday.
The people involved had attended the quarter-mile sprint event at Lawrence earlier in the day and Sgt Kerrisk believed disorderly behaviour had also occurred at another hotel.
Although he was not prepared to say if the two matters were linked, he did say it was disappointing to have two separate incidents at country hotels in the space of a couple of hours.
Senior Constable Robert Wallace, of Lawrence, said there were some "ongoing incidents" throughout the afternoon at hotels from Lawrence through to Central Otago after the quarter-mile event concluded.
Extra police staff were rostered on for the weekend because the event attracted a large crowd.
There were some incidents of disorderly behaviour, including fighting, in Lawrence on Saturday, and an 18-year-old Wanaka man was arrested for assault with a weapon, wilful damage and escaping from police custody.
An Alexandra man would also face charges relating to an incident of disorder.
• A middle-aged couple were lucky to escape injury when a rock was thrown through the back window of their parked car in Alexandra on Friday night, Sgt Kerrisk said.
They were parked outside a dairy in Centennial Ave, eating their dinner, when a van containing a group of people aged from 12 to 20 drove past, throwing rocks at parked cars.
The couple were "extremely shaken" by the incident, Sgt Kerrisk said.
• A 20-year-old Cromwell man has been arrested for disorderly behaviour and a 14-year-old girl would be referred to youth aid on the same matter.
Alexandra police are seeking a 20-year-old man in connection with two assaults at the Alexandra pie cart on Friday night.
Two pie-cart patrons were assaulted and the offender presented a knife, Sgt Kerrisk said.
"We're aware of his identity and believe he's left the area but we're treating this matter very seriously and suggest the man surrender himself to police."
