A young man who "almost completely sliced his buttocks off" after falling through glass was a streaker at a Cricket World Cup game earlier this year.

Fergus Watts was at an event ahead of the University of Canterbury's annual Tea Party on Friday when the incident occurred shortly after midday.

An ambulance officer told 3 News he had "almost completely sliced his buttocks off".

A southern police communications centre spokesman confirmed he had suffered serious injuries to his buttocks and legs and "would not be sitting down for a long time yet" as a result.

Police had dealt with up to four people in relation to drunkenness at the festival but "nothing too serious," he said.

A Canterbury District Health Board spokesman said Watts was in a stable condition in Christchurch Hospital and "doing well".

He had requested no further information be released about his case.

Watts was in June discharged without conviction for running naked on to the field during the Cricket World Cup game between England and Scotland in Christchurch on February 23.

Judge David Saunders found that "stupidity can't be legislated against" and instead of imposing a conviction ordered him to pay a donation to the Westpac Rescue Helicopter Trust.

The university's Tea Party is an annual event celebrating the end of the academic year.

It included a number of activities at Ilam Field, including a water slide, free food trucks, a foam tent and other circus rides, as well as a main music stage.
