Friends and family have spoken to media around the world and paid tribute on social media to those murdered and injured in Friday's shootings at two of the city's mosques.
Here's a list of what we know so far.
THE DEAD
Muse Nur Awale
Awale's death was announced by the Federation of Islamic Associations of New Zealand, who said he was aged 77.
Moshin Al-Harbi
Mohsin Al-Harbi (63) is the only victim who survived the initial attack but later died in hospital. His wife Manal was so distressed as she frantically searched for him, she collapsed and had a heart attack. She was in a critical condition as of Monday morning.
Mucad Ibrahim.
Mucad Ibrahim, 3
Three-year-old Mucad Ibrahim is thought to be the youngest victim.
The toddler had gone to the Al Noor Mosque on Deans Ave with his older brother, Abdi, and his father.
Mucad was lost in the melee, as Abdi fled for his life and his father pretended to be dead after being shot.
The family searched in vain for the toddler at Christchurch Hospital and later posted a photo of Mucad, smiling with Abdi, along with the caption: "Verily we belong to God and to Him we shall return. Will miss you dearly brother."
Abdi Ibrahim described his little brother as "energetic" and "playful" and said he "liked to smile and laugh a lot". He confessed he felt nothing but "hatred" for his brother's killer.
Tariq Omar, 24
Omar's father confirmed his death. According to CNN, Rosemary Omar dropped her son off at the mosque then drove round the back to find a parking space when she heard multiple gunshots. She drove back to the front and saw "lots of bodies outside".
Abdullahi Dirie, 4
Four of Adan Ibrahin Dirie's five children managed to escape, but the youngest, Abdullahi, was killed, said his uncle, Abdulrahman Hashi (60), a preacher at Dar Al-Hijrah Mosque in Minneapolis.
Adan Dirie also suffered gunshot wounds and was hospitalised.
The family fled Somalia in the mid-1990s as refugees and resettled in New Zealand.
"You cannot imagine how I feel," Hashi said. "[Abdullahi] was the youngest in the family. This is a problem of extremism. Some people think the Muslims in their country are part of that, but these are innocent people."
Muhammad Suhail Shahid
One of nine Pakistani deaths announced by authorities in Pakistan.
Syed Jahandad Ali
A senior developer at tech firm Intergen, the 34-year-old was killed at the Al Noor mosque. Married with children, Ali was originally from Pakistan.

Ahmed moved from Karachi for a job in New Zealand 18 months ago to help support his family back home. One of his uncles, Muhammad Muzaffar Khan, described Ahmed (27) as deeply religious, praying five times a day.
Education was always his first priority, Khan said.
"He had done chartered accountancy from Pakistan. He was the only son to his parents. He had only one younger sister ... He had only started his career."
Ahmed worked for PwC, who posted a tribute to him on Facebook calling him a "loved and respected" member of their family.
"His smile, warmth, dedication, respect and humour will be deeply missed," the post read.
Family and friends have gathered at Ahmed's house, where his body is expected to arrive in the coming days.
The family was told Ahmed and a friend had arrived at the mosque just before the shooting began. His friend survived because he was parking the car.
Naeem Rashid, 50
Rashid died at Christchurch Hospital after trying to wrestle a gun from the shooter at the Al Noor Mosque.
Originally from Abbottabad, where he worked in a bank, the 50-year-old became a teacher after moving to Christchurch.
His brother-in-law Dr Khursheed Alam confirmed to ARY News that he had been killed in the attack.
Alam told the BBC he was proud of Naeem Rashid's bravery.
"I've heard from a few people there, there were few witnesses … they've said he saved a few lives there by trying to stop that guy. It's a still a shock for us, whatever hero he becomes … it's our pride now, but still the loss. It's like cutting your limb off."
Talha Rashid, 21
Talha Rashid was Naeem Rashid's oldest son. Aged 11 when the family moved to New Zealand, he had got a new job and was hoping to get married soon, the BBC reported.
"A few days ago when I spoke to Naeem, he told me about his plans to come to Pakistan and get his son married," said Talha Rashid's uncle in Lahore.
"But now we are making arrangements to bring the dead bodies of both father and son back to Pakistan."
Another of Naeem Rashid's sons was being treated for his injuries.
Mahmood leaves behind a wife and two children, aged 13 and 11.
Since completing his doctorate, Mahmood had been working as assistant academic director of Canterbury College, a private school for English language and business students.

His family and friends had been seeking information after al-Umari failed to return after going to Friday prayers at the Al Noor Mosque
His mother, an Iraqi calligraphy artist named Janna Ezzat, wrote on Facebook that her son had become a martyr.
"Our son was full of life and always put the needs of others in front of his own."
12-year-old boy
Heba Sami, whose father was shot and injured protecting his children, told Gulf News that she lost five family friends, including a 12-year-old boy, in the attack.
Sayyad's father has spoken through tears of his "brave little soldier", who died at the Al Noor Mosque.
The Year 10 Cashmere High School was at the mosque with his mother and friends. He attends every Friday.
His father John Milne told NZME through tears: "I've lost my little boy, he's just turned 14. I'll get it together again.
"I haven't heard officially yet that he's actually passed but I know he has because he was seen.
"[I'm] keeping it together and tears are helping. people are helping. Just by being here, it is helping."
He said he was told Sayyad was lying on the floor in the mosque, bleeding from the lower parts of his body.
He said Sayyad was a keen football player.
"I remember him as my baby who i nearly lost when he was born. Such a struggle he's had throughout all his life. he's been unfairly treated but he's risen above that and he's very brave. A brave little soldier. It's so hard ... to see him just gunned down by someone who didn't care about anyone or anything.
"I know where he is. I know he's at peace."
Milne said he has been carrying around a sign in Christchurch which reads "everyone love everyone"
The principal of Cashmere High was going to visit the family soon.
"The community is shattered," Milne said.
"The Muslim community just don't know what to do, where to go, what's happened. They're finding it very hard to accept but there is so much support from so many different people, people who aren't Muslim. Support across the board.
"But we are the most beautiful city rising out of the dust. We will go forward. this won't bring us down. It will make us even stronger. United we stand, divided we fall ... the city is going to be a symbol of what it can do after it has been hit and hit and hit."
Milne's other son usually went to the mosque but was on a school trip. His twin sister was at school when it happened.
Mustafa and his family thought they had found safety in New Zealand after fleeing the bloody chaos of Syria only a few months ago.
But it was in New Zealand that he was shot while praying with his two sons.
Hamza is missing feared dead and Zaid (13) is recovering from a six-hour operation on his wounds at Christchurch Hospital.
Ali Akil, a spokesman for Syrian Solidarity New Zealand, said Mustafa's wife and daughter, who were not at the mosque on Friday, were in "total shock, devastation and horror".
"They survived atrocities and arrived here in a safe haven only to be killed in the most atrocious way.
"They were just looking for a safe place. Unfortunately we can't claim that New Zealand is a safe place anymore."
Five Indian citizens killed
India's ambassador to New Zealand issued the following names of Indian citizens who were killed in the mosque attacks: Maheboob Khokhar, Ramiz Vora, Asif Vora, Ansi Alibava and Ozair Kadir.

Husna Ahmed, 45
Farid Ahmed refuses to turn his back on his adopted home, despite losing his 45-year-old wife, Husna Ahmed, in the Al Noor Mmosque attack.
They had split up to go to the bathroom when it happened.
The gunman livestreamed the massacre on the internet, and Ahmed later saw a video of his wife being shot. A police officer confirmed she died.
Despite the horror, Ahmed — originally from Bangladesh — still considers New Zealand a great country.
"I believe that some people, purposely, they are trying to break down the harmony we have in New Zealand with the diversity. But they are not going to win. They are not going to win. We will be harmonious."
Mohammad Imran Kahn, 47
Kahn owned two restaurants in Christchurch.
Outside one of them, the Indian Grill, yesterday, a handwritten cardboard sign said simply CLOSED. A handful of pink flowers were laid nearby.
The owner of the shop next door, Jaiman Patel (31) said he helped the staff with keys after the terrorist attack that claimed Khan's life.
"He's a really good guy. I tried to help him out with the setup and everything," Patel said.
Khan had a son who was 10 or 11, Patel said.
"We are helping each other. It's so sad."
Amjad Hamid, 57
The heart doctor moved to New Zealand from Palestine because they wanted a better future.
Hamid hasn't been seen since Friday and his family believe the Hawera Hospital doctor is dead.
His wife Hanan said she and her husband emigrated to Christchurch 23 years ago.
"It's terrible ... we were hoping to find a better future for us and for the children we were planning to have."
She described her 57-year-old husband as a "very kind man", but struggled to say more.
"It's hard to talk about him."
The elder of the couple's two sons, 22-year-old Husam Hamid, said family had checked hospitals and with police but there had been no sign of his dad since the mass shootings began.
Amjad Hamid was known to go to the mosque to pray on Fridays.
"At first I thought he went to the Linwood mosque but he was most likely to have been in the Deans Ave mosque as he mostly goes to that one ... we are presuming that he is dead, but we don't know."
According to his LinkedIn profile, Hamid was a consultant in cardiorespiratory integrated specialist services at Canterbury District Health Board for 20 years, but his son said he had recently taken up a role in cardiology at Hawera Hospital in south Taranaki.
He rotated three weeks working at the hospital with three weeks at his Christchurch home, Husam Hamid said.
Family had gathered to support each other, but it was tough.
"This is meant to be a safe country. New Zealand is changing forever."
His mother was "struggling", he said.
"My mum, she loves him so much."
Youngest son, Mohammed Hamid (20) said they had checked everywhere but his dad couldn't be found.

The airline confirmed Lilik Abdul Hamid, an aircraft maintenance engineer in Christchurch, was in the mosque at the time of the attacks.
He was married with two children.
Air NZ chief executive officer Christopher Luxon said the airline was devastated.
"Lilik has been a valued part of our engineering team in Christchurch for 16 years, but he first got to know the team even earlier when he worked with our aircraft engineers in a previous role overseas," he said.
"The friendships he made at that time led him to apply for a role in Air New Zealand and make the move to Christchurch. His loss will be deeply felt by the team.
"Lilik, his wife Nina and their children Zhania and Gerin are well known and loved by our close-knit team of engineers and their families, who are now doing all they can to support the family alongside our leadership team and the airline's special assistance team.

Daraghmeh said Waseeim moved to New Zealand five years ago and described it as the "safest place one could ever live in."
The Daraghmehs are of Palestinian origin, but have Jordanian citizenship.
The Palestinian Foreign Ministry said Saturday at least four Palestinians were killed, but acknowledged they could have been counted by Jordan or other countries.
Shihadeh Nasasrah, 63
Nasasrah spent terrifying minutes lying underneath two dying men as the gunman kept firing.
The assailant "would go out and bring more ammunition and resume shooting," said Nasasrah, speaking by phone from Christchurch Hhospital where he was recovering from two shots to the leg.
"Every time he stopped, I thought he was gone. But he returned over and over again. I was afraid to leave because I didn't know the safest way out. I died several times, not one time
Mohammed Elyan

Muath Elyan said his brother helped establish the mosque a year after arriving in New Zealand, where he teaches engineering at a university and runs a consultancy.
His brother last visited Jordan two years ago.
"He used to tell us life was good in New Zealand and its people are good and welcoming. He enjoyed freedom there and never complained about anything. I'm sure this bloody crime doesn't represent the New Zealanders."
Muhammad Amin Nasir, 67
Nasir and his son were just 200 metres from the Al Noor mosque when everything went wrong.
A car driving by stopped suddenly and a man leaned out the window pointing a gun at them.
They ran but Muhammad Nasir could not keep up with his 35-year-old son. He sustained critical injuries.

Zulfirman Syah and son Averroes
Alta Marie said her husband Zulfirman Syah shielded their son, Averroes, during the attack at Linwood Masjid.
Syah's bravery meant he was hit with multiple bullets and sustained much more complex injuries than their son Averroes, she said.
Late last night, in a social media post, she wrote: "He is in stable condition following the extensive exploratory and reconstructive surgery he had earlier today. While he is still in the intensive care unit at this stage, he will be moved to the general ward whenever it is deemed appropriate (likely in the next day or so).
"While the road to recovery will be long, his condition has only improved since he arrived at the hospital yesterday. This afternoon he had a visit from the Indonesian ambassador, which lifted his spirits.
"Averroes (our son) sustained minor injuries and had surgery this morning to extract some shrapnel while checking for internal injuries. He is recovering nicely and has been cheerful while keeping the staff on the children's ward entertained with his talkative and energetic nature.
"I am grateful that my family members are alive, as many lives were lost during these attacks. Please keep those people in your thoughts and prayers."
The family moved to Christchurch two months ago.
Dr Mohammad Alayan
