The Christchurch mosque shooter will appear before the Auckland High Court on Thursday.
Brenton Tarrant is currently serving a sentence of life imprisonment without parole for murdering 51 people and attempting to murder 40 others at two Christchurch mosques on March 15 2019. He was also convicted last year for committing a terrorism offence.
He will appear before Justice Geoffrey Venning on Thursday morning seeking a judicial review and will represent himself.
It's understood Tarrant wants the Court to review decisions made about his prison conditions and also his designation as a "terrorist entity" under the Terrorism Suppression Act.
The judicial review will have no bearing on the outcome of the case, Tarrant's conviction or the sentence imposed on him.
A judicial review is where a judge is asked to review an action or decision that has been made under a legal power. The judge will look at whether the way the decision was made was in accordance with the law, but won't usually decide whether the decision was the right one.
The Ministry of Justice says that about 180 judicial reviews are heard every year.
Tarrant was sentenced in Christchurch last August after pleading guilty to all 92 charges earlier in the year. It was the first time a sentence of life in prison without parole has been passed down in New Zealand. He has been in jail at Paremoremo's Auckland Prison ever since, living in solitary confinement.
He is able to have some visitors and Newshub reported last year he is able to watch television two hours a day in his cell.
Corrections said following his sentencing that Tarrant would be "managed under the most stringent custodial regime we have ever developed", and they're committed to ensuring he causes no harm, directly or indirectly to anyone.
