Prime Minister Jacinda Ardern says the Christchurch mosque shooting is attempting to "revictimise people" by appealing his convictions and sentence.
She refused to extensively comment on Brenton Tarrant's application for appeal filed in the Court of Appeal.
"I made a pledge a long time ago that I would not publicly name the terrorist from March 15," Ardern told reporters on Tuesday.
"That is because his is a story that should not be told, his is a name that should not be repeated, and I am going to apply that same rule in commenting on his attempts to revictimise people. We should give him nothing."
Ardern has refused to name the terrorist since the shooting at two Christchurch mosques on March 15, 2019.
Justice Minister Kiri Allan said her thoughts were with victims.
"I am thinking about the victims of the crime of a terrorist, somebody who pleaded guilty to terrorism. I don't have too much more to add to be quite frank."
Tarrant, an Australian, was convicted and sentenced to life in prison after pleading guilty to murdering 51 people, attempting to murder 40 others and a terrorism charge.
The Wellington Court of Appeal has confirmed to Newshub that an application for appeal against Tarrant's convictions and sentence has been filed. No hearing date has been set.
Tarrant's sentence of life in prison without parole was the first time such a punishment has been handed down in New Zealand.
He has been in jail at Paremoremo's Auckland Prison living in solitary confinement.
