Tarrant was depicted showing the so-called OK gesture, which some associate with the white supremacy movement.
The video footage showed a man driving to the mosque, entering it and shooting randomly at people inside. The camera attached to his head recording the massacre follows the barrel of his weapon, like some macabre video game.
Another person who died was a Jordanian man, the former general secretary of the Canterbury Muslim Association, who "liked to serve the people and ... give advice". He got through to ambulance and told them: "There's a big massacre, please send help and call the police because they're continuously shooting".
The unnamed man went home to retrieve his gun when the shooting broke out before returning to the Linwood mosque to engage the shooter. "One leg of an injured needed to be amputated while another suffered bullet injuries in his chest", Rahman Bhuiyan said. No images have emerged from the second mosque.
Police also found improvised explosive devices attached to two vehicles outside of one of the mosques.
Ms Ardern confirmed two of the 40 people who were being treated for injuries at the Christchurch Hospital were in a critical condition, while a five-year-old child had been transported to Starship Hospital in Auckland.
Players and members of the team's coaching staff were reportedly on their bus, approaching the Masjid Al Noor mosque in Hagley Park when the shooting broke out.
Two other people were being held in custody and police said they were trying to determine how they might be involved.
ASSOCIATED PRESSPolice officers search the area near the Masjid Al Noor mosque, site of one of the mass shootings at two mosques in Christchurch, New Zealand on Saturday. Eleven people remained in intensive care, hospital authorities said. Funerals were planned on Saturday for some of the victims, several of whom were born overseas. "New Zealand is home for all of us, and this despicable act will not change that feeling of closeness in us". Bolton said the U.S.is in touch with New Zealand officials to offer assistance.
The victims of Friday's shooting included immigrants from Jordan, Saudi Arabia, Turkey, Indonesia and Malaysia.
"I'm not sure how to deal with this".

He said he chose New Zealand because of its location, to show that even the most remote parts of the world were not free of "mass immigration". "The offender was in possession of a gun licence" obtained in November 2017, and he started purchasing the weapons the following month, she said.
Ardern said following the incident, the country's gun laws will have to change.
Four New Zealand women hugged each other outside the cordon.
But that visit, and the kindness of his hosts, did not deter Tarrant from his homicidal plans, which he said he had been formulating for two years - but had not originally meant to act on in New Zealand.
Two semi-automatic weapons, two shotguns and lever-action gun were used in the attacks.
"We do have gun control".
"Fijian hearts are breaking for our brothers and sisters in New Zealand - a place where an atrocity of this nature is shocking nearly beyond comprehension".
Leaders around the world expressed sorrow and disgust at the attacks, with some deploring the demonisation of Muslims.
"The United States strongly condemns the attack in Christchurch".
Ardern, who arrived in Christchurch on Saturday, said the shooter was not on any watchlist and did not have a criminal record.
"Part of that is addressing those types of things and fears that might be present now within the Muslim community of Saskatoon", he said.
Political and Islamic leaders across Asia and the Middle East voiced concern over the targeting of Muslims. It is only further confirmation of the pernicious spread of Islamophobia and other forms of racism, emboldened by the ascent of far-right parties across the developed world and the activation of the (only barely latent) ideology of white supremacy embedded in the history and body politic of these nations. "1.3 billion Muslims have collectively been blamed for any act of terror".
