This callous act in Auckland will stir painful memories of the deadly mosque attacks in Christchurch in 2019.
In that attack, a lone gunman – a self-confessed white supremacist – murdered 51 worshippers. Once again, New Zealand’s geographic isolation and peaceful reputation have proved to be no defence against extremism.
The assailant had, for years, been identified as a threat to national security and was under 24-hour surveillance.
The police acted decisively to prevent further carnage, but they weren’t close enough to stop serious injuries. New terror laws could, however, allow volatile individuals to be detained in the future.
Australian Prime Minister Scott Morrison has sent a message of support: Kia Kaha New Zealand, he wrote, using Maori words. Stay strong.
