Facebook says anyone in New Zealand searching its site for extremist content will in the future be directed to websites helping people to leave hate groups. It began doing this in the United States in March and overnight it announced it is rolling out the scheme in Australia and Indonesia, with New Zealand next on the list. It's among a raft of policy changes it says were partly prompted by the Christchurch Call - a move to limit online extremist content that was initiated in Paris by Prime Minister Jacinda Ardern and French President Emmanuel Macron in the wake of the mosque attacks. Internet New Zealand took part in the Paris meeting, and their engagement director Andrew Cushen has been looking over Facebook's announcement.
