History

Historical Context

On 15 March 2019 Australian white supremacist Brenton Tarrant livestreamed attacks on Christchurch’s Al Noor Mosque and Linwood Islamic Centre, killing 51 worshippers—the deadliest terrorist act in New Zealand. The city, still rebuilding from the 2011 magnitude-6.3 earthquake that killed 185, had already endured major trauma, intensifying national calls for tighter online-extremism controls and policy reforms.
