Alexandra police are likely to make further arrests in relation to an incident in the town at 4am yesterday.
A 26-year-old man and 23-year-old woman, both of Alexandra, were arrested and charged with assault after police were called to a disturbance at a residential address in Ellis St.
Sergeant Andy Reed, of Alexandra, said police were called to reports of people yelling.
"A group of associates had a bit of a falling out. Injuries were minor," he said.
Sgt Reed said further charges would likely be laid, against those already arrested, as well as others involved in the incident.
Cromwell police attended two car crashes near the town yesterday, although no-one was injured in either incident.

No other vehicles were involved, and nobody was arrested.
About 2pm, tourists travelling along SH6 towards Queenstown in the Kawarau Gorge stopped suddenly to turn into the Roaring Meg power station lookout.
A truck driver traveling behind the tourists did not have time to slow down and crashed into the back of their vehicle.
