On 15 March 2019, two consecutive terrorist mass shootings took place in Christchurch, New Zealand. They were committed during Friday prayer, first at the Al Noor Mosque in Riccarton at 1:40 p.m., and shortly afterwards at 1:52 p.m. at the Linwood Islamic Centre. In total, 51 people were killed and 89 others were injured, including 40 by gunfire. The perpetrator was identified as Brenton Tarrant, a 28-year-old Australian man at the time.
Tarrant was arrested after his vehicle was rammed by a police car as he was driving to a third mosque in Ashburton. He live-streamed the first shooting on Facebook, marking the first successfully live-streamed far-right terror attack, and had published a manifesto online before the attack. On 26 March 2020, he pleaded guilty to 51 murders, 40 attempted murders, and engaging in a terrorist act, and in August was sentenced to life imprisonment without the possibility of parole – the first such sentence in New Zealand.
The attacks were mainly motivated by white nationalism, anti-immigrant sentiment, and white supremacist beliefs. Tarrant described himself as an ecofascist and professed belief in the far-right "Great Replacement" conspiracy theory in the context of a "white genocide".
The attack was linked to an increase in white supremacy and alt-right extremism globally observed since about 2015. Politicians and world leaders condemned it, and the prime minister, Jacinda Ardern, described it as "one of New Zealand's darkest days". The government established a royal commission into its security agencies in the wake of the shootings, which were the deadliest in modern New Zealand history and the worst ever committed by an Australian national. The commission submitted its report to the government on 26 November 2020, the details of which were made public on 7 December.
The shooting has inspired multiple copycat attacks, especially due to its live-streamed nature. In response to this incident, the United Nations designated 15 March as the International Day to Combat Islamophobia.
The gunman first attacked the Al Noor Mosque on Deans Avenue in the suburb of Riccarton, opposite Hagley Park. It was opened in 1985, the first mosque in the South Island. Shortly after, he attacked the Linwood Islamic Centre on Linwood Avenue, 6 km away in the suburb of Linwood: it was opened in 2018.
Brenton Harrison Tarrant (born 27 October 1990), a white Australian man from Grafton, New South Wales, who perpetrated the shootings, was 28 years old at the time of the shootings. After his arrest, Tarrant told investigators that he frequented right-wing discussion boards on 4chan and 8chan and also found YouTube to be "a significant source of information and inspiration".
Tarrant arrived in New Zealand in August 2017 and lived in Andersons Bay in Dunedin until the shootings. He was a member of a South Otago gun club, where he practised shooting at its range.
Tarrant wrote a 74-page manifesto entitled The Great Replacement, a reference to the "Great Replacement" and "white genocide" conspiracy theories. Minutes before the attacks began, the manifesto was emailed to more than 30 recipients, including the prime minister's office and several media outlets, and links were shared on Twitter and 8chan. Seven minutes after Tarrant sent the email containing the manifesto to parliament, it was forwarded to the parliament security team, who instantly called the police communication centre at 1:40 p.m., around the same time the first 111 calls were made from the Al Noor Mosque.
In the manifesto, several anti-immigrant sentiments are expressed, including hate speech against migrants, white supremacist rhetoric, and calls for all non-European immigrants in Europe whom he claimed to be "invading his land" to be removed. The manifesto displays neo-Nazi symbols though he denies being a Nazi, describing himself instead as an "ethno-nationalist", and an "eco-fascist".
The manifesto was described by some media outlets as "shitposting"—a form of trolling designed to derail conversations and provoke strong reactions from people not in the know. Readers of the manifesto described it as containing deliberately provocative and absurd statements, such as sarcastically claiming to have been turned into a killer by playing violent video games. On 23 March 2019, the manifesto was deemed "objectionable" by the Chief Censor of New Zealand, making it unlawful to possess or distribute it in New Zealand. Exemptions to the ban were available for journalists, researchers, and academics. In August 2019, The New Zealand Herald reported that printed copies of the manifesto were being sold online outside New Zealand, something New Zealand law could not prevent.
In the manifesto, Tarrant also claimed that China is the nation that most aligns with his political and social values. He had a stated aim of polarising and destabilising the West and to spark a civil war in the United States so as to force a "separation of races".
Tarrant started planning an attack about two years prior to the shootings, and chose his targets three months in advance. Some survivors at the Al Noor Mosque believed they had seen Tarrant there on several Fridays before the attack, pretending to pray and asking about the mosque's schedules. The Royal Commission report found no evidence of this, and police instead believe that Tarrant had viewed an online tour of Al Noor as part of his planning.
On 8 January 2019, Tarrant used a drone operated from a nearby park to investigate the mosque's grounds. Additionally, he used the Internet to find detailed mosque plans, interior pictures, and prayer schedules to figure out when mosques would be at their busiest levels. On the same day, he had driven past the Linwood Islamic Centre.
Police recovered six guns: two AR-15 style rifles (one manufactured by Windham Weaponry and the other by Ruger), two 12-gauge shotguns (a semi automatic Mossberg 930 and a pump-action Remington Model 870), and two other rifles (a .357 Magnum Uberti lever-action rifle, and a .223-calibre Mossberg Predator bolt-action rifle). Tarrant was granted a firearms licence with an "A" endorsement in November 2017, and purchased weapons between December 2017 and March 2019, along with more than 7,000 rounds of ammunition. He used four 30-round magazines, five 40-round magazines, and one 60-round magazine in the shootings. Additionally, he illegally replaced the semi-automatic rifles' small magazines with the higher capacity magazines purchased online, against the conditions of Tarrant's gun licence.
The guns and magazines used were covered in white writing naming historical events, people, and motifs related to historical conflicts, wars, and battles between Muslims and European Christians; as well as the names of recent Islamic terrorist attack victims and the names of far-right attackers. Some of the markings were white supremacist slogans such as the anti-Muslim phrase "Remove Kebab" and the number "14", a reference to Fourteen Words.
His armoured vest had at least seven loaded .223/5.56 magazines in the front pockets. He also wore an airsoft helmet, which held the head-mounted GoPro he used for his live stream. Police also found four incendiary devices in Tarrant's car; they were defused by the New Zealand Defence Force. He said, on the livestream, that he had planned to set the mosque on fire.
The shootings, which were the deadliest terror attack committed in New Zealand and by an Australian citizen, took place at two separate venues. Fifty-one people aged between 3 and 77 died in the attacks, including one victim who died in the hospital: 44 at the Al Noor Mosque and seven at the Linwood Islamic Centre. The dead comprised 43 men, 4 women, and 4 boys. As well as the 51 dead, 89 people were injured, 40 from bullet wounds.
