College principal Jack Saxon confirmed in a release to parents, that further investigation was occurring to determine whether the pupil acted alone and called on anybody who had received the video to delete the material immediately.
"Given the severity of this matter, I have decided to suspend the student from school pending a hearing from the Board of Trustees," he said.
"This incident is incredibly serious and has the potential to significantly impact the wellbeing of the victim both now and into the future."
Saxon would not disclose any details around the content of the video but did not rule out further disciplinary action.
"I would encourage you to continue to be an upstander and call out members of our school community who continue to video learners without their permission," he said.
"At the end of the day our chief role as educators is to create a safe environment, both physically and mentally for the learners that come here."
Mount Hutt College staff received several disclosures from school pupils which Saxon described as "critical in minimising the potential impact on the victim".
The use of cell phones at the school is set to come under review which could lead to a change in school policies.
"Any major incident that occurs at our school will lead to a review around the systems we have in place to support our akonga," Saxon said.
"In this case, we are likely to focus specially around the purpose in enabling cell phone use in school."
It is unclear as to whether the footage was shared with pupils at other schools in the district.
Ashburton College principal Ross Preece said he was unaware of the alleged incident and would not be drawn on questions around whether any of his pupils had received the footage.
Two pupils at Ashburton College were excluded in 2018, following a schoolyard attack which was also caught on camera.
