Officers arrested two others following the attacks and are now working to establish whether they had any involvement in the terror attacks against the Muslim community in New Zealand. "We as a health system are here to support everyone in our community".
Prime Minister Jacinda Ardern called the incident "an extraordinary act of unprecedented violence" and "New Zealand's darkest day".
"They may take our innocence but we will show the world the meaning of love and compassion", said one note taped to flowers left on a road divider.
At one stage the shooter returns to his vehicle, changes weapons, re-enters the mosque and again begins shooting. He remains the only person charged in relation to the attacks, Bush said.
"It's been 36 hours, I haven't heard anything about them", he said.
Outside one of the two mosques, 32-year-old Ash Mohammed pushed through police barricades in hopes of finding out what happened to his father and two brothers, whose cellphones rang unanswered.
A video live-streamed by him on Facebook showed him rapidly firing what appeared to be hundreds of bullets at his defenseless victims using various weapons.
Mr Morrison said he has been in contact with Ms Ardern, and that Australian agencies are working with New Zealand authorities.
CNN has not been able to independently confirm any information about the attackers or the alleged video. "49 innocent people have so senselessly died, with so many more seriously injured". It was not signed.
Another 48 people are reported to have suffered gunshot wounds, with some of them in critical condition.
A friend of Wasseim's, Carolyne Phillips, who was at the hospital with him, said he had undergone surgery for a perforated bowel, an injury to his pelvis and to get shrapnel and bone out of his hip socket.
Brenton Tarrant remained silent and looked at journalists in the gallery.
Police urged all mosques across New Zealand to stay closed over the weekend for security reasons.
He did not request bail and was taken into custody until his next court appearance scheduled for April 5.
He is one of three people arrested in connection with the shooting; and while the other two remain in custody, their role remains unclear.
The staff member monitoring the accounts sent it to parliamentary services as soon as they saw it, who sent it to police, the spokesman said.
During a Saturday press conference, Ardern said the gunman had two semi-automatic weapons, two shotguns, and a lever-action firearm (five firearms in total). Dunedin is about 225 miles from Christchurch.
He also apparently smirked at photographers, according to the New Zealand Herald. A woman apprehended at the scene was released without charge.
"But that arrest was tangential to this matter and we do not believe that he was involved in this attack either", he said.
