Tarrant was remanded into custody and is expected to appear in court again on April 5.
"There is one charge of murder brought at the moment, it is reasonable to assume that there will be others", said the judge, whose name was not reported by the AP.
Tarrant has been described as a suspected white supremacist, based on his social media activity. No images have emerged from the second mosque. Ardern labeled the carnage a terrorist attack and has vowed to change the country's gun laws as a result.
Two other armed suspects were taken into custody Friday while police tried to determine what role, if any, they played in the cold-blooded attack that stunned New Zealand, a country so peaceful that police officers rarely carry guns. None of those arrested had a criminal history or were on watchlists in New Zealand or Australia. One more died in hospital, where another 48 wounded are still receiving care, two in a critical condition. 39 remain in the hospital, 11 of whom are in the ICU, Ardern said. So, I worry when I'm driving or when I'm at work and I'm like, does the person next to me that's the person next to me share these thoughts? The gunman donned a helmet video camera and broadcast live footage of his rampage on Facebook akin to the carnage of shoot-em-up video games. "Hi guys how are you".
"I came to the street, I saw one person got shot on his chest", he said, adding that the ambulance and police then arrived on the scene. "I convey the message of love and support on behalf of New Zealand to all of you, she said". Ardern said some were from Pakistan, Turkey, Saudi Arabia, Bangladesh, Indonesia and Malaysia. "I'm not sure how to deal with this".
One other man was arrested on Friday for carrying a firearm in his auto in order to get to his family home while the city was in lockdown, and was released by police without charge.
National carrier Air New Zealand canceled at least 17 flights in and out of Christchurch, saying it couldn't properly screen customers and their baggage following the shootings.
One man who said he was at the Al Noor mosque told media the gunman burst into the mosque as worshippers were kneeling for prayers.
The shooter broke into two mosques in Christchurch on Friday, opening fire on those who were inside.
"And that's why we can all stand together in support of our Muslim brothers and sisters who were the specific targets of this attack".
For an Islamic funeral burial is traditionally within 24 hours of death. Later in the day, it emerged that he used five guns in Friday's attack, including two shotguns and two semi-automatic weapons. That number has grown consistently throughout the years, with New Zealand reporting only 1.3 million such firms in 2016, 1.2 million in 2009 and less than a million in 2005.
"The offender was in possession of a gun licence" obtained in November 2017, and he started purchasing the weapons the following month, she said.
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 quake.
The White House released a statement condemning the attacks.
President Donald Trump told Prime Minister Jacinda Ardern by phone that the United States stood in solidarity with New Zealand.
"He loves his family", said Shaik.
Leaders around the world expressed sorrow and disgust at the attacks, with some deploring the demonisation of Muslims. None of them had been on any security watch lists prior to the attack, officials said.
