[9][10] On 15 March 2019, White supremacist Brenton Tarrant staged two consecutive mass shootings at the Al Noor Mosque and Linwood Islamic Centre in Christchurch, killing 51 people.

[22] 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.

[27] In late October, Marshall confirmed that she plans to examine the initial response to the attacks by emergency services and whether any victims could have been saved if things had been done differently.

[31] On 24 February, Tarrant's lawyer Ron Mansfield KC told the Coroner that his client was seeking an appeal of the earlier Royal Commission of Inquiry's hearings on the basis of factual errors in their report.

[32] That same day, the Islamic Women's Council's national co-ordinator Aliya Danzeisen told the Coroner about the dangers of online "radical movements" operating on 4Chan and Telegram promoting hatred and violence against the Muslim community and undermining democracy and the rule of law in light of the 2022 Wellington protests.

Coroner Windley is expected to examine a large amount of evidence including nearly 3,000 documents, 4,750 images, 2,720 audio files, and over 80 hours of video.

That same day, the Inquest heard that the Police had not immediately dispatched personnel to the Linwood Islamic Centre despite being told that the mosque was a potential target during an emergency call.

[36] On 27 October, the Inquest heard testimony from the 111 call-taker's supervisor who defended the Police's decision not to raise the priority level of the emergency call regarding the mosque attack.

[37] On 30 October, the Inquest heard testimony from an Armed Offenders Squad (AOS) officer who had responded to the shooting at Al Noor Mosque, operations commander Detective Superintendent Darryl Sweeney, and senior police communicator Bret Watkins.

[39] On 1 November, the Inquest heard testimony that members of the Armed Offender Squad and paramedics had delayed providing first aid to victims at Al Noor Mosque due to fears that the gunman was still at large.

[46] On 10 November, the Inquest heard that AOS personnel used their own vehicles to evacuate the wounded at Linwood centre since ambulances were held up at Al Noor Mosque.

"[47] On 13 November, the Inquest heard testimony from an Australian police officer that paramedics spent six minutes on the road while he and AOS members persuaded them to proceed to Linwood Islamic Centre.

Critical care paramedic Dale Muller disputed the police officer's account and defended the response of St John's Ambulance and other emergency staff.

"[52] That same day, Senior Sergeant Roy Appley was questioned by counsel assisting coroner David Boldt about the coordination between Police and St John Ambulance staff responding to the Linwood mosque attack.

[53] On 28 November, a senior police tactical operator testified that AOS members had expressed frustration at the perceived delayed response of ambulance staff in responding to their calls for help at Al Noor Mosque.

[54] On 29 November, former St John dispatcher Dawn Lucas for accidentally alerting Police to an active shooter event at the Christchurch Hospital's emergency department.

Detective Senior Sergeant Craig Farrant also acknowledged that they had investigated two "persons of interests" who had alluded to attacks on Al Noor Mosque prior to 15 March 2019.

During questioning, Chubb also acknowledged that St John's had not been aware about the whereabouts of its Special Emergency Response Team (SERT) personnel during the attacks.

[61] On 11 December, British counter-terrorism expert Julian Platt testified that Police could have stopped the attack against Linwood Islamic Centre had they been aware of the threat against it.

That same day, Fire and Emergency New Zealand (FENZ) commander Brendan Nally defended the organisation's decision not to deploy firefighters in response to the mass shootings, stating that they were not trained to deal with armed shooter incidents and did not have access to ballistic protection.

[63] On 14 December, Dr John Hick testified that delays and confusion in mass shooting events like the Christchurch terror attack were not uncommon.

Deputy chief coroner Windley along with counsel for the Police, St John's, Fire and Emergency, as well as families of the victims and survivors made closing statements.

[6][33] Following the First Phase Inquest, the Inquiry is expected to look at the Police's firearms licensing process, Tarrant's online activities, and the community's ability to detect and response to violent extremism.

[68] On 28 May, Al Noor Mosque survivor Khaled Al-Nobani gave testimony arguing that the failure of the main emergency door did not contribute to the number of lives lost during the massacre.

[71] The clerk also told the inquest that Tarrant had been categorised as "fit and proper" under the firearms licensing process, which at the time relied on a "high trust" model dependent on the applicant and referees to tell the truth.

[73] That same day Windley, victims' lawyer Kathryn Dalziel and coroner's counsel Ian Murray questioned the two referees about their interactions with Tarrant.

[74] On 11 October the former police vetting officer, who had interviewed Tarrant for his firearms license application, described the terrorist as a "good actor that was clearly hiding something more sinister.

Lauren told the inquest that Tarrant had developed an admiration for Adolf Hitler, Oswald Mosley and Nigel Farage after returning from his overseas travels in 2016.

[77] On 17 October University of Canterbury sociologist Dr Jarrod Gilbert told the inquest that Tarrant would have had difficulty obtaining firearms from New Zealand gangs due to his lack of criminal history and connections, and his White supremacist ideology.

[79] On 24 October, the second-phase inquest adjourned with clsoing statements being made by Windley, victims' lawyers Kathryn Dalziel, Fatima Ali, Amir Bastani, and Kerryn Beaton KC.
