"It is possible that communicating about the 'games' could unintentionally promote interest and involvement. The key issue is to look out for the signs of risk and be able to recognise and respond to young people who may need help."
Te Tai Tokerau Primary Principals chairman and Onerahi school head Gerald Koberstein welcomed the ministry taking a proactive inter-agency approach to issues affecting youth in the region.
"The times have changed. A lot of children's social interaction used to be at school, but because of social networking it's moved beyond school.
"Having an inter-agency group that's there to support schools, communities and families when these traumatic things happen is a really proactive thing to do. That sort of support is great."
While schools had clear internet and social media policies it was up to parents to keep an eye on what their youngsters were doing at home and it was important to check on what young people were doing via social networking.
"We recommend that you and your staff remain alert to the potential for students' involvement in the 'blackout game', be mindful about young people's internet and technology use and are prepared to support them to communicate about things they may be hearing, writing or receiving," the letter said.
Any schools with concerns about this issue or needing further support can ring the Ministry's Traumatic Incident helpline on 0800 848 326 or Child Youth and Family on 0508 FAMILY (0508 326 459).
The ministry concerns come as the region tackles a dramatic increase in youth suicides. Of the 32 suspected cases this year, 12 were in the 10 to 19 age group. The region averaged about three suspected suicides in that age group annually.
