The gunman opened fire on two mosques in the city on 15 March last year and killed 51
A New Zealand court has sentenced the man who shot dead 51 people at two mosques to life in prison without parole.
Australian Brenton Tarrant, 29, pleaded guilty to the murder of 51 people, attempted murder of another 40 people and one charge of terrorism, reports BBC.
During the sentencing he was confronted by survivors and relatives of victims.
The gun attacks at the two mosques sent shockwaves around the world. In the wake of the killings, New Zealand brought in stricter gun laws.
What happened during the sentencing?
The sentencing hearing lasted four days and more than 60 victim impact statements were heard.
On the last day of statements, Koranic verses were read out and photos of loved ones were shown to the court.
Maysoon Salama, whose son died in the attack, said Tarrant "terrorised the whole of New Zealand and saddened the world".
Sara Qasem, whose father Abdelfattah Qasem died at the Al Noor Mosque, said he was a "shining glimmering man".
She spoke about the last moments of her father's life, 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. But I couldn't do that."
The gunman chose not to speak in court before Thursday's sentencing.
What happened in Christchurch?
The gunman opened fire on two mosques in the city on 15 March last year.
He first targeted worshippers inside the Al Noor mosque. Less than 30 seconds later, he returned to his car to pick up another weapon and then re-entered the mosque and resumed firing on those inside.
The entire incident was broadcast on Facebook Live via a headcam he was wearing.
He then drove to the Linwood Islamic Centre where he shot two people outside and then shot at the windows.
A man from inside rushed outside and picked up one of the attacker's shotguns before chasing him away.
Two police officers then chased and arrested the gunman. After his arrest, he told police that his plan was to burn down mosques after his attack and he wished he had done so.
During this week's sentencing, the court heard that the gunman planned to target another mosque but was detained by officers on the way.
How did New Zealand respond?
The attack prompted New Zealand to reform its gun laws.
Less than a month after the shootings, the country's parliament voted by 119 to 1 on reforms banning military-style semi-automatic weapons as well as parts that could be used to build prohibited firearms.
The government offered to compensate owners of newly-illegal weapons in a buy-back scene.
Prime Minister Jacinda Ardern has said that "much more" needs to be done to stop radicalisation in the country.
"The challenge for us will be ensuring in our everyday actions, and every opportunity where we see bullying, harassment, racism, discrimination, calling it out as a nation," she said on the first anniversary of the attacks.
