The university last night apologised and said it ''deeply regrets'' the injuries that occurred in the Commerce Building.
Chief operating officer John Patrick said the university tried hard to make its campus safe.
''It is clear that in the case of the Commerce Building it failed.''
The apology came after Auckland woman Katherine Casey on Monday received $60,000 in reparation from the university, after she was left with permanent injuries following a fall in the atrium of the building.
In a private prosecution in the Dunedin District Court this week, the university pleaded guilty to a Health and Safety in Employment Act charge of failing to take action to ensure the safety of flooring for persons walking across it, knowing that failure was likely to cause serious harm.
The university has also promised a $15million refit of the building. The design is to be completed by April next year, and construction by mid 2017.
Ms Casey brought the prosecution after she fell on slippery tiles in the atrium of the building in 2013, breaking her pelvis in three places, and her spine.
Victoria Casey, her lawyer and sister, yesterday released a list of 82 complaints from 1993 to last year, and university responses, released by the university under the Official Information Act.
Injuries listed included a broken arm, dislocated arm and sprained ankle from slipping on tiles in three incidents in 1993 alone, before one complainant in 1996 fell on wet stairs, fracturing their jaw and breaking two teeth.
In 1998 a person in shock was taken to hospital with thigh, knee and lower leg injuries after a fall on the atrium steps, while another broke their spine and a finger.
The documents also show the university was clearly told there was a problem.
In 2001, the Otago University Students' Association presented a petition with 1049 signatures, noting the tiles were ''lethal''.
That same year one person suffered a torn liver, and another a broken arm after slipping on the tiles.
Bruising, broken ankles and fractures continued, and in 2010 a 9 year old child slipped, fell, and was knocked unconscious.
The university last night said it now had an online occupational health and safety management system for reporting incidents, near misses and hazards, but Mr Patrick said ''it is clear the university has failed to adequately manage the safety issues in the Commerce Building''.
It had taken responsibility for that by pleading guilty to the charges.
Victoria Casey late yesterday responded to an earlier media release from the university, which apologised for ''the distress to the complainant involved in this case''.
It said the university had ''worked hard to try to resolve this person's concerns''.
Victoria Casey said her sister did not suffer ''distress''. Rather she was seriously injured and would be living with those injuries for the rest of her life.
''And the others who were seriously injured on these tiles similarly weren't just 'distressed'. Perhaps they also should be acknowledged.
She said Judge Kevin Phillips had been critical on Monday of the way the university had treated Ms Casey and her husband over the past two years.
