The second-year student, who did not want to be named, said yesterday he felt he was being treated unfairly.
"What I did was definitely not worthy of expulsion."
It has become traditional for older students to throw eggs, flour bombs and water balloons at first-year students as they walk along George St dressed in togas during the February Orientation parade.
However, this year's parade descended into mayhem, with some onlookers also throwing bottles and faeces.
George St retailers were appalled the next morning to find several signs and windows broken and the footpath and shopfronts splattered with rubbish, blood and vomit, as well as eggs and flour. The event received extensive media coverage in New Zealand and overseas.
The student does not deny throwing eggs at parade participants. He was photographed in mid-throw by an Otago Daily Times photographer. However, he said several other people in the same photograph were also throwing eggs.
"They are facing nothing as severe as I am. It doesn't seem very fair," he said.
As far as he is aware, he is the only person facing expulsion. Asked how he felt about that, he said, "Obviously, not very good."
The student said he had been told by the university proctor the university planned to expel him. Today is his chance to argue his case before an appeals board.
He said he was "a little bit nervous" about the meeting.
University spokeswoman Megan McPherson said yesterday other students were also facing disciplinary measures but would not say how many.
Otago student magazine Critic, which broke the student's story in this week's edition, said the student had been given a final warning by the university at the end of last year to improve his behaviour or face expulsion after a series of alcohol-fuelled incidents. They included urinating in public, attempting to set a couch alight and exposing himself to Campus Watch staff.
When asked yesterday if he had done those things, the student replied "ah ha". But he said he had learnt from his mistakes, paid the price for those incidents, and settled down to his studies this year.
