Blood was allegedly left smeared on the floor and over items owned by clubs after a private function at the Green Island Civic Hall.
The Dunedin City Council says it is disappointed and is investigating the incident.
A social media user slammed the users in an anonymous post, labelling their behaviour "disgusting".
The hall had been left with sticky booze-covered floors, and blood on floors and on items owned by clubs.
A club involving children and young adults had been left disappointed after having to cancel their plans to use the hall on a subsequent night due to the damage.
‘‘There is no excuse for this type of animalistic behaviour . . . shame on everyone that attended,’’ the user said.
A DCC spokesman confirmed the venue was damaged.
"We are always disappointed when our venues are damaged or left in poor condition. It is a requirement that these spaces are left tidy and ordered when they are hired out, and it is a shame this was not the case with this event.
"We are still investigating the incident and working with affected parties."
