Christchurch is a city of about 400,000 residents, still recovering from a massive quake in 2011 that killed 187 people.
Among the wounded, two were in a critical condition, including a four-year-old child.
"I've lived next door to this mosque for about five years and the people are great, they're very friendly", he said.
New Zealand police commissioner Mike Bush said on March 16, the morning after the massacre, that authorities have no information about any imminent threats in the country but that everyone should continue to be vigilant in the wake of mass shootings at two mosques.
"It's outrageous" he said. The nationalities of the victims included Indian, Pakistani, Malaysian, Indonesian, Egyptian, Bangladeshi, Saudi, Somalian and Turkish, authorities said. One victim posted a Facebook video from his hospital bed, asking for prayers for himself, his son and daughter.
The audio recording of Ardern's press conference was published by New Zealand Herald.

Huang Yan, the manager of the Christchurch branch of China's Southern Airlines, told Xinhua the mass shooting would bring negative impact on New Zealand tourism as Christchurch has just been recovered from the aftermath of the 2011 deadly natural disaster.
Although shops were shuttered and many chose to stay at home Saturday, bouquets of flowers piled up at a makeshift memorial near the Al Noor mosque, many accompanied with handwritten letters laden with sadness and disbelief. "I will keep watch while you pray". "Our hearts are breaking for your loss", read one of the notes marked with a string of x-kisses. All the weapons were legally obtained. Ardern said some of the guns had been modified to make them deadlier.
"While work has been done as to the chain of events that led to both the holding of this gun licence and the possession of these weapons, I can tell you one thing right now: our gun laws will change", Ardern told reporters. The video showed a man driving to the Al Noor mosque, entering it and shooting randomly at people with a semi-automatic rifle with high-capacity magazines.
The prime minister continued by adding that the charged individual was in custody 36 minutes after the police received the first call about the incident.
A fourth person who was detained in the aftermath of the attack was later determined to be an armed bystander who wanted to help police.
A man who could not find out information about what happened to his father and two brothers pushed through police barricades at one of the cordons in an effort to get closer.
The suspect was remanded in custody without plea to the High Court in Christchurch on April 5.
Despite this latest tragedy, Wahb said the local Muslim community will do its best to maintain business as usual. "The Muslims have a deep command taught to be intertwined with the whole, so it is sad to see that some people hate us". Police said the alleged shooter was arrested in a vehicle, which was carrying improvised explosive devices, 36 minutes after they were first called.
The attack has prompted searching questions about whether right-wing extremism has been treated with enough seriousness by Western governments.More news: Reputed Boss Of Gambino Crime Family Gunned Down In New York
