Schools need to adjust learning policies to cater for the iPod generation to counter cyber bullying, a Western Bay Principal warns.
Faced with a whole generation of teenagers who only know "iPods, iPads and iPhones", schools need to teach online safety, and ensure new technologies can be incorporated in student learning, Mount Maunganui College principal Russell Gordon said.
Police are investigating two separate cases of cyber bullying after videos of students fighting were posted on social media sites.
Students from at least three Hamilton schools were filmed in fights at a park on Monday afternoon. The footage, taken on a digital camera phone, showed girls and boys brawling and was posted on YouTube.
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.
"The police were informed immediately [after] we became aware of the seriousness of what had occurred."
Principal Gordon stressed the importance of creating a safe school environment.
"We had an organisation come in and speak to our year 9 and 10s ... and our seniors about online etiquette earlier this year.
"A lady from NetSafe is coming down in two weeks to speak to the year 9 and 10s again."
Students had to understand that whilst it was not a right, it certainly was a privilege to be online and have access to technology, Mr Gordon said.
NetSafe executive director Martin Cocker said bullies used online videos to exert 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 change 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 proposed law to crackdown 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.
At least one in five New Zealand high school students have reported being victims of cyber bullying.
Cyber bullying includes use of the internet, mobile phones or other technology to hurt, harass or embarrass another person.
Vodafone customers can use its Blacklist service to block certain people from messaging them.
