Police have said the man - who can not yet be named - was not involved in the attack in Christchurch allegedly carried out by Australian white supremacist Brenton Tarrant, 28, on Friday. Tarrant- a suspected white supremacist - live-streamed the attack from inside the Masjid Al Noor Mosque on Friday shortly after prayers.
"It's good for the world to see what's happened because people around the world, they thought we were terrorists because some stupid people, they said they are Muslims, they go and kill innocent people, they thought we are terrorists", said Abulaban who emigrated to New Zealand from Jordan 17 years ago.
"There will be changes to our gun laws", Ardern said at a news conference.
Gun City owner David Tipple said Tarrant bought the weapons and ammunition between December 2017 and March 2018.
Tarrant, who appeared in court on Saturday charged with murder, on Monday sacked his state-appointed lawyer.
In the wake of Friday's horrific mass-shooting in Christchurch that left 50 people dead and scores more fighting for their lives in hospital, New Zealand's gun laws have come under enormous public pressure as those across the country try to come to terms with the shocking tragedy.
Jacinda Ardern said Cabinet ministers had met and made an in-principle decision to tighten gun ownership but details still need to be worked out.
"We have listened to public sentiment following Friday's terrorist attack in Christchurch and chose to remove all semi-automatic firearms sales and parts associated with those weapons today", Trade Me's statement reads.
Ardern has announced that New Zealand will hold a national commemoration service to mark the attack.
Prime Minister Jacinda Ardern has vowed to change the country's gun laws.
Kiwibank, the Bank of New Zealand, and the Australia and New Zealand Banking Group have also independently pulled most or all of their ads from Facebook.
Families of the 50 people killed in the Christchurch mosque shootings are enduring an increasingly agonizing wait for the bodies of victims to be released as New Zealand reels from the unprecedented tragedy. A gun shop owner said the attacker purchased four guns from him through a "police-verified online mail order process", but it was unclear whether any of those firearms were used in the shootings.
A teenager, whose name can not be published, appeared in court on Monday and was charged with distributing that footage. There was a sense of safety in coming together on Monday, she said.
He said that the firearm was not purchased from Gun City.
The organisers of New Zealand's largest gun show - the Kumeu Militaria Show, near Auckland - announced on Monday they had cancelled the event in the wake of the massacre and because of "elevated security risks".
"We detected nothing extraordinary about the licence holder. But it is at the discretion of the family", said Mo, who asked to be identified by just one name.
Facebook said it removed 1.5 million videos of the shootings during the first 24 hours after the massacre. "He was a brand new purchaser, with a brand new license".
