The man behind the massacre Brenton Tarrant, 29, admitted to the killing of 51 people, attempted murder of another 40 people and one charge of terrorism.
The judge called Tarrant’s actions “inhuman”, saying he “showed no mercy”.
The bloodshed which was live streamed occurred in March 2019. which was livestreamed. The devastating incident shocked the world.
The sentencing of Tarrant also marks the first terrorism conviction in New Zealand’s history.
“Your crimes are so wicked that even if you are detained until you die, it will not exhaust the requirements of punishment,” said Judge Cameron Mander in a Christchurch court on Thursday.
On imposing a sentence of life without parole, Justice Mander said: “If not here, then when?”
A sentence without parole means the offender will not be given the opportunity to leave prison after serving only a portion of their total sentence.
Justice Mander said such life sentences without parole were reserved only for the “very worst murders”.
New Zealand does not have the death penalty as part of its justice system.
New Zealand Prime Minister Jacinda Ardern, upon hearing of Tarrant’s sentencing, said it meant he would have “no notoriety, no platform… and we have no cause to think about him, to see him or to hear from him again”.
“Today I hope is the last where we have any cause to hear or utter the name of the terrorist,” she said.
The shootings prompted New Zealand to pass stricter gun laws and buy back certain types of weapons from owners.
On the final day of a four-day sentencing hearing, Justice Mander spent almost an hour reminding Tarrant of each person he killed and injured.
He added that despite the gunman’s guilty pleas, the gunman appeared “neither contrite nor ashamed”.
Tarrant, who said through a lawyer in court that he did not oppose the prosecution’s application for a life without parole sentence, did not react to the sentence. He had earlier also refused the right to speak at his sentencing.
The sentencing hearing began on Monday, with a large part of the first three days dedicated to hearing victim impact statements.
Tarrant appeared largely without emotion and unrepentant over the past three days, as almost 90 victims – some grieving, others defiant – confronted him.
Sara Qasem, whose father Abdelfattah Qasem died at the Al Noor Mosque, spoke of the last moments of his death, saying: “I wonder if he was in pain, if he was frightened, and what his final thoughts were. And I wish more than anything in the world that I could have been there to hold his hand and tell him it would all be OK.”
She struggled to hold back her tears, before looking at Tarrant and saying “these tears are not for you”.
Ahmed Wali Khan a resident who lost his uncle in the attacks, told reporters that the Muslim community in Christchurch were in support of the verdict.
“Everyone was quite happy that justice has been served,” he said, adding that the community had been “waiting for this decision for a very long time”.
Taj Kamran, an Afghan refugee who was shot several times in the leg and still requires walking aids, said he would “be able to sleep” after the verdict, though it would not return those who were lost.
“No punishment is going to bring our loved ones back and our sadness will continue for the rest of our lives,” he said
