New Zealand gun laws
New Zealand's parliament backs changes to gun laws after last month's deadly mosque attacks.
Ms Ardern has been addressing the New Zealand parliament over a proposed ban on all types of semi-automatic weapons and assault rifles following the Christchurch attacks. "These weapons were designed to kill, and they were designed to maim and that is what they did on the 15th of March," Ms Ardern said.
The New Zealand PM has promised changes to firearms regulations in the wake of Friday's attack.
