Emergency services responded to ‘‘multiple calls’’ to the student street about 11pm.
Two patients transported to Dunedin Hospital in a moderate condition, a Hate Hone St John spokesman said.
One man was injured by a bottle thrown into the crowd, Senior Sergeant Anthony Bond, of Dunedin, said.
He received an open wound on his right forearm which needed stitches.
A second person was transported to hospital after falling unconscious.
She was conscious and alert by the time they left in the ambulance, Snr Sgt Bond said.
St John sent one first response unit and one rapid response vehicle.
Police received reports of an assault on Castle Street North, a spokeswoman said.
‘‘It appears that there was a disorder incident at the time in the area and many noise complaints.’’
