The case of the Australian man accused of the Christchurch mosque terrorist attacks is returning to New Zealand's High Court to determine the most appropriate site for his trial next year.
Brenton Tarrant will appear via videolink from an Auckland jail in a court hearing on Thursday.
The nature of the crime, New Zealand's deadliest peacetime shooting, has led his lawyers, Shane Tait and Jonathan Hudson, to apply to move the trial from Christchurch.
A suppression order over the hearing means the content and argument may not be made public until a decision is made by High Court Justice Cameron Mander.
Tarrant, 29, issued a plea of not guilty to his charges - 51 counts of murder, 40 counts of attempted murder and one charge of terrorism - in June.
The case is the first charge of terrorism brought before a New Zealand court.
Justice Mander previously cleared Tarrant of the need for a fitness hearing to stand trial.
The trial is due to begin on June 2 next year, four weeks later than originally planned after the Crown requested the date be shifted to avoid a clash with the Muslim holy month of Ramadan.
The mass shooting has led to major gun law reform in New Zealand, with Prime Minister Jacinda Ardern also pursuing an international agreement between countries and major tech companies to eradicate extremist content on the internet.
