Three men have been arrested following a Christchurch street brawl at the weekend in which police say pot plants, a spade, baseball bat and a metal street sign pole were used as weapons.

The Saturday night fracas in the Dallington area of the city involved two groups of men, police said.

Three men were injured, with one hospitalised with an 11cm cut to his head and significant cuts and bruises to his body.

Another was knocked out and treated for a minor head wound and cut. They were both discharged from hospital on Sunday morning.

A third man is reported to have received multiple bruises to his back and body.

Three men, aged 17, 20 and 22, now face a variety of charges, including assault with a weapon. They are due to appear in Christchurch District Court on Thursday.

"It appears that two groups of men have used weapons in the form of pot plants, a spade, a baseball bat and a pole that is thought to have been removed from a street sign," Detective Sergeant Chris Power said.

Police investigations are ongoing and they are appealing for witnesses.

"Police are keen to speak to a fourth man described as Maori/Polynesian, 17-18 years of age, thin build and estimated to be 185cm tall or taller," a police statement said.

"The Dallington neighbourhood [has] been working hard to minimise crime in the area and police are working with the community and the two groups to resolve the issues that led to this disagreement."
