Background
On 15 March 2019, two consecutive terrorist attacks targeted mosques in Christchurch, New Zealand, during Friday (Jumu'ah) prayers. The attacks struck the Al Noor Mosque in the suburb of Riccarton and the Linwood Islamic Centre in the suburb of Linwood. In total, 51 people were killed and dozens more were wounded, making it the deadliest mass shooting in modern New Zealand history and one of the worst acts of terrorism the country has experienced.
The perpetrator was Brenton Harrison Tarrant, an Australian-born man who was 28 years old at the time of the attacks. He had been living in Dunedin, New Zealand, and had legally obtained firearms licences. Tarrant espoused white supremacist and anti-immigrant ideology and identified with the racist conspiracy theory known as the 'Great Replacement.' Before the attacks, he published a lengthy manifesto online outlining his extremist motivations.
The Attack
Shortly after 1:40 p.m. local time, Tarrant entered the Al Noor Mosque on Deans Avenue, where hundreds of worshippers had gathered for Friday prayers, and opened fire with semi-automatic weapons. The majority of the victims were killed there. He livestreamed part of the attack on social media using a head-mounted camera, broadcasting the violence in real time. The footage spread rapidly online before platforms moved to remove it.
After leaving the first mosque, Tarrant drove to the Linwood Islamic Centre several kilometres away and opened fire on worshippers there, killing several more people. At Linwood, a worshipper named Abdul Aziz Wahabi confronted the gunman, chasing him and helping to disrupt the attack. The victims ranged widely in age, including children and elderly people, and came from numerous countries within the Muslim community of Christchurch.
Response and Investigation
Police apprehended Tarrant approximately 21 minutes after the first emergency call, ramming his vehicle and arresting him while he was still armed and reportedly en route to a possible third target. New Zealand authorities treated the attacks as terrorism from the outset, and the response involved national police, intelligence agencies, and emergency services.
Prime Minister Jacinda Ardern condemned the attacks and pledged to deny the perpetrator notoriety, declining to speak his name publicly. Within weeks, the New Zealand government enacted sweeping reforms to firearms law, banning most semi-automatic weapons and military-style firearms and launching a buy-back scheme. A Royal Commission of Inquiry was later established to examine the circumstances surrounding the attacks and potential failures in detecting the threat.
Perpetrator and Trial
Brenton Tarrant was charged with 51 counts of murder, 40 counts of attempted murder, and one charge under the Terrorism Suppression Act. He initially pleaded not guilty but in March 2020 reversed his pleas and pleaded guilty to all charges, avoiding a full trial.
In August 2020, the High Court in Christchurch sentenced Tarrant to life imprisonment without the possibility of parole. It was the first time such a sentence had been imposed in New Zealand. During the sentencing hearing, survivors and victims' family members delivered numerous victim impact statements directly addressing the court. The judge described the crimes as so wicked that a finite sentence could not be justified, even accounting for time the offender would spend in prison.
Aftermath and Legacy
The attacks prompted an outpouring of solidarity in New Zealand and globally. Vigils were held, and many New Zealanders, including non-Muslims, observed gestures of support for the Muslim community. The phrase 'They are us,' used by Prime Minister Ardern, became emblematic of the national response.
In the wake of the attacks, New Zealand and France co-led the 'Christchurch Call,' an international initiative bringing together governments and technology companies to combat the spread of terrorist and violent extremist content online. The Royal Commission of Inquiry's findings, released in late 2020, examined intelligence and policing shortcomings and made numerous recommendations. The shootings also intensified global discussion about online radicalisation, the role of social media in amplifying extremist content, and the threat of far-right terrorism.
