Jacinda Ardern on the Christchurch Call: How New Zealand led a movement

During a Global Stage livestream conversation hosted by GZERO in partnership with Microsoft on the sidelines of the UN General Assembly, the former New Zealand Prime Minister Jacinda Ardern revealed that when she reached for her phone to share the heartbreaking news of the Christchurch massacre, she found a horrifying surprise: A livestream of the massacre served to her on a social media platform.


For a period of 24 hours, copies of the footage were uploaded to YouTube as often as once per second, spreading the 17-minute massacre faster than tech companies could shut it down.

The experience drives her work at the Christchurch Call, combating online extremism and working with government and civil society to build guardrails against the exploitation of technology by extremists, , she explained during a Global Stage livestream conversation hosted by GZERO in partnership with Microsoft on the sidelines of the UN General Assembly.
