The party's online page calls on revellers to ''invite everyone and anyone'' and that the party would be ''kicking off from sunrise'' on July 11.
''No glass. Street will be cleaned by residents the following day,'' the page says.
A host for the party warned off those not legally allowed to drink.
''Can 15-year-olds please refrain from attending. We don't want you here,'' he posted after a young teenage girl indicated she was attending.
A police spokesman said they were aware of the event.
''We will be monitoring any event which does happen and take appropriate action where necessary,'' he said.
''As with any large party police are aware of, staff will be speaking with the organisers to make sure relevant planning is in place.''
An university spokeswoman said Campus Watch would talk to the residents and explain possible consequences if any issues resulted from the event.
Student residents would also be reminded of the university's code of conduct, she said.
The university did not respond to a question about whether they would attempt to stop the party.
Otago University Students' Association president Paul Hunt said party attendance might be exaggerated.
''I think it's probably important to point out that the Facebook numbers potentially overstate the number of people who will attend,'' Mr Hunt said.
The association would have to ''consider the issue more carefully'' before going to the step of asking the party's organisers to call off the party, he said.
''I can understand why the community would be worried, but before we make a definitive call we will need to seek more information and clarity around what is actually planned.''
It would speak to the party's organisers.
''What we usually do is go and chat to people about being good hosts, like having water and food present and minimising the amount of glass and being respectful of property,'' he said.
The event's no-glass policy and call to clean up the next day showed the organisers were ''acutely aware of the need to look after themselves and other members of the community'', he said.
