Christchurch shooter’s appeal wraps up in NZ court as he pleads guilty; attack sparked global rise in mosque security concerns.
As of February 2026, Brenton Tarrant, convicted for the 2019 Christchurch mosque shootings, is appealing his 2020 guilty pleas in New Zealand's Court of Appeal. He claims harsh prison conditions caused mental illness, impairing his ability to plead rationally. The five-day hearing will decide if his pleas are quashed, potentially leading to a new trial and sentence appeal.
