New Zealand mosque shooter seeks to discard his guilty pleas, saying prison made him irrational

WELLINGTON, New Zealand — The man who killed 51 Muslim worshipers at two mosques in New Zealand's deadliest mass shooting told an appeals court Monday that he felt forced to admit to the crimes because of ''irrationality'' due to harsh prison conditions, as he sought to have his guilty pleas discarded.

A panel of three judges at the Court of Appeal in Wellington will hear five days of evidence about Brenton Tarrant's claim that he was not fit to plead to the terrorism, murder and attempted murder charges he faced after the 2019 attack in the city of Christchurch. If his bid is successful, his case would return to court for a trial, which was averted in March 2020 when he admitted to the hate-fueled shooting.

He is also seeking to appeal his sentence of life without the chance of parole, which had never been imposed in New Zealand before. Tarrant's evidence Monday about his mental state when he pleaded guilty was the first time he had spoken substantively in a public setting since he livestreamed the 2019 massacre on Facebook.

Shooter says he suffered ''nervous exhaustion''

The Australian man, a self-declared white supremacist, migrated to New Zealand with a view to committing the massacre, which he planned in detail. He amassed a cache of semiautomatic weapons, took steps to avoid detection and wrote a lengthy manifesto before he drove from Dunedin to Christchurch in March 2019 and opened fire at two mosques.

Along with 51 people killed, the youngest a 3-year-old boy, dozens of others were severely wounded. The attack was considered one of New Zealand's darkest days and institutions have sought to curb the spread of Tarrant's message through legal orders and a ban on possession of his manifesto or video of the attack.

Monday's hearing took place under tight security constraints that severely limited who could view Tarrant's evidence, which included some reporters and those hurt or bereaved in the massacre. Tarrant, who wore a white button-down shirt and black-rimmed glasses and had a shaved head, spoke on video from a white-walled room at Auckland Prison.

By the time he pleaded guilty, Tarrant said he was suffering from ''nervous exhaustion'' and uncertainty about his identity and beliefs. He had admitted to the crimes a few months before his trial was due to begin because there was ''little else I could do,'' he told the court.

Crown lawyers say no evidence of serious mental illness

Crown lawyer Barnaby Hawes suggested to Tarrant during questioning that the Australian man had other options. He could have requested a delay in his trial date on mental health grounds or could have proceeded to trial and defended himself, Hawes said.

Hawes also put to Tarrant that there was little evidence in the documentation of his behavior by mental health experts and prison staff that he was in any kind of serious mental crisis. Tarrant suggested that signs of mental illness he displayed hadn't been recorded and that at times he had sought to mask them.

''I was definitely doing everything possible to come across as confident, assured, mentally well,'' he told the court. Tarrant's behavior ''reflected the political movement I'm a part of,'' he added. ''So I always wanted to put on the best front possible.''

The appeal outcome is due later

Bids to appeal convictions or sentences in New Zealand must be made within 20 working days. Tarrant was about two years late in seeking an appeal, filing documents with the court in September 2022.

He told the court Monday that his bid had been late because he hadn't had access to the information required to make it.
