Further north, a video showing a 14-year-old Northland student being beaten up by classmates was posted on Facebook and YouTube. The Ruawai College student was attacked in the school bathrooms while a group of students looked on and filmed.
Two students, aged 15 and 16, have been thrown out of the college and face charges in the Youth Court. Two younger students have been referred to Police Youth Aid.
Principal Stephen Fordyce said the "criminal event" happened in September and had caused great distress.
Speaking to The Daily Post yesterday, Mr Walker stressed that anything posted online lasted forever.
"In the past we've had issues of silly fights that then get filmed.
"Sometimes when we've investigated, we've found that the fights are pretend and just a set-up anyway," he said. "Other times they've been fighting and name-calling."
Teenagers often failed to understand that even things which were staged looked different when viewed online, Mr Walker said.
NetSafe executive director Martin Cocker said bullies used online videos to show superiority. "The bullying is about exerting power over another person.
"Posting a fight of where you win, or the other person is a victim, increases the power imbalance between you.
"It's a logical bullying system."
Young people often failed to understand the repercussions of bullying, Mr Cocker said.
In one of New Zealand's worst cases of cyber bullying, 15-year-old Wanganui schoolgirl Robin de Jong was filmed being chased down and assaulted by another student last year. Footage of her attacker punching and kicking her until she was unconscious was captured on another pupil's cellphone.
Rotorua teenager Hayley-Anne Fenton took her own life four years ago after receiving abusive text messages from her boyfriend's wife. The case sparked calls for changes to social media regulation.
Coroner Wallace Bain found the overarching cause for Hayley-Anne's death was the "shocking bullying" texts she had received.
The Government is currently considering a new law to crack down on internet bullies.
It includes the formation of a Communications Tribunal which would deal with online harassment cases. Offensive posts on Facebook and Twitter and hurtful text messages would become a new criminal offence.
