As news of the incident spread a post appeared on the Rotorua Boys' High memes page on Facebook, which stated the page apologised for the incident on behalf of the school.
The post stated: "If you guys didn't know, a single year 11 JPC was beaten up by a large group of RBHS students early this morning.
"This kind of behaviour is disgusting, and is not in any way condoned by this page. It's all fun and games when we joke about it and make memes about neighbouring schools, but when it becomes physical and people are targeted, then this has been taken too far.
"I hope most of you aren't involved, and hope those who were get punished to the full extent possible. We are here to make light-hearted jokes about ours, and other schools in Rotorua and do not want to hurt anybody in this way. To the JPC student that was attacked, I would like to personally apologise on behalf of RBHS, and wish you a speedy recovery."
Mr Grinter said the students involved in the incident had been dealt with by the school and their families informed of what had happened.
The fight was because of comments which had been posted on Facebook about a girl by a John Paul College student. Mr Grinter said a Boys' High student was a friend of the girl and took exception to the online comment. Students were being reminded about how quickly things could escalate in an online forum.
