New Zealand PM Jacinda Ardern vows never to utter name of Christchurch gunman

acinda Ardern, New Zealand Prime Minister, vowed on Tuesday never to utter the name of the twin-mosque gunman as she opened a sombre session of parliament with an evocative "as salaam alaikum" message of peace to Muslims.

"He will face the full force of the law in New Zealand," Ms Ardern promised grieving Kiwis, while promising that she would deprive the man who slaughtered 50 people in Christchurch of the publicity he craved.

"He sought many things from his act of terror, but one was notoriety," she told assembled lawmakers of the 28-year-old Australian accused of the slaughter.

"That is why you will never hear me mention his name. He is a terrorist. He is a criminal. He is an extremist. But he will, when I speak, be nameless."

"I implore you: Speak the names of those who were lost rather than the name of the man who took them."

Lawyer Richard Peters, who was assigned to represent Brenton Tarrant at his initial court appearance on Saturday, told the New Zealand Herald that Tarrant dismissed him that day.

A judge ordered Tarrant to return to New Zealand's High Court on April 5 for his next hearing on one count of murder, though he is expected to face additional charges. The 28-year-old Australian is being held in isolation in a Christchurch jail.

Dressed in black, the 38-year-old prime minister opened her remarks in parliament with the symbolism of the greeting uttered across the Islamic world.

"Wa alaikum salaam wa rahmatullahi wa barakatuh" she said –’May the peace, mercy, and blessings of Allah be with you too.’

She closed her address by noting that "on Friday, it will be a week since the attack, members of the Muslim community will gather for worship on that day. Let us acknowledge their grief as they do."

The shooter's desire for attention was made clear in a manifesto sent to Ms Ardern's office and others before Friday's massacre and by his livestreamed footage of his attack on the Al Noor mosque.

The video prompted widespread revulsion and condemnation. Facebook said it removed 1.5 million versions of the video during the first 24 hours, but Ms Ardern expressed frustration that the footage remained online, four days later.

"We have been in contact with Facebook; they have given us updates on their efforts to have it removed, but as I say, it's our view that it cannot - should not - be distributed, available, able to be viewed," she said. "It is horrendous and while they've given us those assurances, ultimately the responsibility does sit with them."

Ms Arden said she had received "some communication" from Facebook's Chief Operating Officer Sheryl Sandberg on the issue. The prime minister has also spoken with Prime Minister Theresa May about the importance of a global effort to clamp down on the distribution of such material.

Her comments came as dozens of relatives of the deceased began arriving from around the world ahead of expected funerals which have already been delayed far beyond the 24 hours after death usually observed under Islamic custom.

The slow process of identification and forensic documentation has so far made burials impossible, augmenting families’ grief.

Javed Dadabhai, who travelled from Auckland to help bury his cousin, said families and volunteers were told: "It is going to be a very slow process, a very thorough process".

"Some families have been invited to have a look at their family members... the ones that are easiest to recognise, but we are talking about three or four."

"The majority of people still have not had the opportunity to see their family members," he told AFP.

In the wake of the mass shooting, Ms Ardern has promised to reform New Zealand gun laws that allowed the gunman to legally purchase the weapons he used in the attack on two Christchurch mosques, including semi-automatic rifles.

New Zealanders have already begun answering government appeals to hand in their weapons, including John Hart, a farmer in the North Island district of Masterton.

Mr Hart said it was an easy decision for him to hand in his semi-automatic and tweeted that "on the farm they are a useful tool in some circumstances, but my convenience doesn’t outweigh the risk of misuse. We don’t need these in our country".

The tweet drew a barrage of derogatory messages to his Facebook account – most apparently from the US, where the pro-gun lobby is powerful and vociferous.

Mr Hart deleted the messages but posted online: "A warm kia ora to all my new American Facebook friends."

"I’m not familiar with your local customs, but I assume ’Cuck’ is a traditional greeting," he said of the insult, short for "cuckold" frequently used by far-right pundits.

Police said they did not have data available on the number of weapons handed in since Friday.

But they issued a statement saying that "due to heightened security and the current environment, we would ask that people please call us first before attempting to surrender a firearm."

Ms Ardern has said that details of the government’s proposed law changes on gun ownership will be announced by next week, but she indicated that gun buybacks and a ban on some semi-automatic rifles were under consideration.

"As the Cabinet, we were absolutely unified and very clear: the terror attack in Christchurch on Friday was the worst act of terrorism on our shores, it was in fact one of the worst globally in recent times, it has exposed a range of weaknesses in New Zealand’s gun laws," she said.
