A man was bottled and transported to Dunedin Hospital with injuries after a 21st party at a rural Otago rugby club erupted into violence, police say.
Acting Senior Sergeant Iain Notman, of Dunedin, said police were called to the disorder in Milton on Saturday evening.
Dunedin police responded to a request for back-up from Milton police as they were dealing with "aggressive patrons at a 21st party at the Toko Rugby Club".
There were reports of "multiple fights", Acting Snr Sgt Notman said.
Back-up arrived and the event settled down.
Later on, police received calls about "further assault and more disorder" from a group related to the 21st party, who had now congregated at a nearby residential address.
No arrests were made and further inquiries were continuing, Acting Snr Sgt Notman said.
Police also removed a man "who received injuries from a bottling", but it was unclear at which event this occurred.
Police transporting the man to Dunedin Hospital themselves.
A member of the public said the bottling occurred at the second gathering.
