Canterbury University students dressed in an array of costumes and a little worse for wear have been given a warning after being arrested during 24 hours of end-of-lecture celebrations.
Christchurch police said in all 73 students were arrested for a breach of liquor bans, with the first being a young man dressed as a "good-looking maid" around 8am on Friday.
All had sobered up by the end of the annual Tea and Garden Party celebrations at 8am on Saturday and had been sent on their way with a pre-charge warning, which meant they would not have to appear in court but the arrest would be recorded.
Senior Sergeant Neru Leifi said the students had obviously put a lot of effort into their costumes, with the standout being one dressed as an Avatar.
"We had to hold them all over the place - in the dayroom and everywhere as our holding cells were full but the majority of them were pretty compliant. They did leave a whole lot of their costumes outside in the garden," he said.
The University of Canterbury Students' Association had warned students not to breach the liquor bans if they wanted to avoid a "night in the slammer".
