About 90 school pupils from Central Otago attended the launch and workshop for online guides: ''Think before you share: hit pause then post'' and ''Help a friend in need'', created by Facebook with the help of Central Otago anti-bullying group Sticks 'n Stones.
They were designed to encourage children to think about what they share online and to look out for their friends on social media.
Videos, games, and sessions were led by Facebook's Australia New Zealand director of policy Mia Garlick, with representatives from Sticks 'n Stones and Australian-based anti-bullying group Project Rockit.
Sticks 'n Stones project facilitator Karla Sanders, of Alexandra, said the workshop was an ''amazing'' opportunity for pupils to take part in an event usually held in ''bigger centres''.
Teachers, police and Central Otago Mayor Tony Lepper were also at the event, held at Cromwell and Districts Presbyterian Church.
