Brenton Tarrant, the Australian white supremacist convicted of murdering 51 Muslim worshippers in New Zealand's 2019 Christchurch mosque attacks, is appealing his guilty pleas, claiming prison conditions impaired his mental state.
The 35-year-old, serving life without parole—New Zealand's first such sentence—argued in Wellington's Court of Appeal that solitary confinement caused "nervous exhaustion," making him irrational when pleading guilty in March 2020 to 51 murders, 40 attempted murders, and one terrorism charge.
Tarrant, who live-streamed the assault and shared a racist manifesto, told the court via video link that harsh isolation with limited contact or reading material left him unable to make informed decisions, feeling he had "little else I could do" before trial.
His former lawyers testified he always intended to admit guilt but sought control over timing, showing no fitness concerns then. A psychologist (Witness B) supported impacts from prison conditions, but forensic expert Professor James Ogloff countered that Tarrant exaggerated distress, rejecting torture claims; prior 2019-2020 assessments deemed him fit to plead. Crown lawyers noted alternatives like trial delays existed, with scant evidence of crisis. The five-day hearing, ending soon, could overturn pleas for retrial or proceed to sentencing appeal.
