New Zealand Prime Minister Jacinda Ardern awed American gun control advocates Friday night when she announced that her administration would promptly pursue changes to her country's gun laws following the shooting deaths of 49 people at two mosques in Christchurch-in stark contrast to the response of the US government to similar attacks.
New Zealand Police Commissioner Mike Bush announced the latest death in a news conference Sunday.
Three other suspects were arrested along with Tarrant on Friday, but police now say he acted alone.
The suspected attacker, who identifies himself as 28-year-old Brenton Tarrant, reportedly acquired a gun license in November 2017.
Australian Prime Minister Scott Morrison earlier confirmed that one of the four people taken into custody is Australian.
Tarrant was arrested in a auto, which police said was carrying improvised explosive devices, 36 minutes after they were first called.
Ardern's office said the suspect sent the "manifesto" by email to a generic address for the prime minister, the opposition leader, the speaker of the parliament and around 70 media outlets just minutes before the attack.
New Zealand has in the past tried to tighten firearm laws, but a strong gun lobby and culture of hunting has stymied such efforts.
The man facing murder charges was an Australian citizen who had spent a lot of time travelling overseas and spent time only sporadically in New Zealand, Ardern said. But he said some people frustrated because "they want to get on with their grieving process".
Tarrant is expected to face additional charges and two others are in custody.
Jacinda Ardern reiterated to the public on Saturday morning that the country's gun law will be changed.
A Jordanian man says his 4-year-old niece is fighting for her life after being wounded in the New Zealand mosque shootings.
"I said to him, 'Calm down, the police are here now, '" Khan said.
At least 49 people were killed in mass shootings at two mosques during midday prayers on Friday and dozens more were wounded, some critically.
Like most developed countries, New Zealand has far stricter gun laws than the United States, where more than 50 shootings involving more than one victim have already taken place this year.
The test was due to start at Hagley Oval in Christchurch on Saturday but the Bangladesh team left New Zealand less than 24 hours after the shooting and about an hour after the initial scheduled start time.
She did not offer too much detail, but said a ban on semi-automatic weapons would be looked at. Armed police were deployed at several locations in all cities, unusual in a country that has had low levels of gun violence.
Tarrant did not apply for bail, and per ABC News reports, did not apply to have his name suppressed.
Ardern said Tarrant was a licensed gun owner who allegedly used five weapons, including two semi-automatic weapons and two shotguns, which had been modified.
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.
Mr Bainimarama also said his government will be working closely with authorities in New Zealand to monitor the welfare of Fijians in Christchurch.
"When people, of course, hear that this individual had acquired a gun licence and acquired weapons of that range, then obviously I think people will be seeking change, and I'm committing to that", Ms Ardern said.
