About 4000 people were attracted to the university's annual show of its more than 100 clubs and societies on campus yesterday.
Race, religion and political beliefs form the basis of many groups, while others are dedicated to outdoor activities, specific sports and the wider arts.
Among the crowds were students signing up to dance, play music, debate the legalisation of marijuana, lobby for political parties, kayak, row, ski and tramp.
Malay, Indian, Japanese and African groups offered cultural experiences, but in the stifling crush of bodies, many turned to the yoga and meditation clubs in search of zen.
Otago University Students' Association (OUSA) Archery Club secretary Leon Deverick said more than 100 people registered their interest in joining the group yesterday.
That was far more beginners than the club could handle at once, he said.
OUSA recreation manager Debbie Coulter said the annual clubs and societies day was always popular, but there seemed to be more people than usual through the doors yesterday.
She said being part of a non-academic group provided students with like-minded friends as well as the chance to become leaders and learn new skills.
"For international students it's also a good way to meet more New Zealanders as well as more people in general," Ms Coulter said.
OUSA club development officer James Grubb said there was a university group for just about everything, including the "wacky, weird and wonderful".
"We've got some very well organised clubs this year and a few others are in the process of becoming affiliated," he said.
