Brenton Tarrant, an Australian white supremacist, is seeking to appeal his convictions for the Christchurch mosque shootings that left 51 people dead in 2019, marking New Zealand's worst mass shooting incident. Initially pleading guilty in March 2020 to multiple charges including murder, attempted murder, and terrorism, Tarrant was sentenced to life imprisonment without parole in August 2020, becoming the first individual in New Zealand to receive such a sentence under current laws.

In 2022, Tarrant submitted an appeal concerning both his convictions and his unprecedented life sentence; however, the court will need to determine if this appeal can advance due to it being filed outside the legally allowed timeframe. As part of the appeal process, he is expected to give evidence via video link during the court proceedings scheduled to take place over a week in Wellington, starting from February 9.

This appeal draws attention not only to the legal aspects surrounding Tarrant's case but also to the broader implications for New Zealand's approach to hate crimes and terrorism. Tarrant's case has had a lasting impact on New Zealand society and policy regarding gun laws and counter-terrorism measures, and the outcome of this appeal may further influence these discussions.
