NBC News reports:
New Zealand Prime Minister Jacinda Ardern announced an immediate ban Thursday on sales of “military-style” semi-automatic firearms and high-capacity magazines in the wake of a terrorist attack on two mosques in Christchurch that killed 50 worshippers. Ardern said the sales ban was effective immediately to prevent stockpiling and would be followed by a complete ban on the weapons after new laws were rushed through.
She said people could hand over their guns under an amnesty while officials develop a formal buyback scheme, which could cost up to 200 million New Zealand dollars ($140 million). The ban includes any semi-automatic guns or shotguns that are capable of being used with a detachable magazine that holds more than five rounds. It also extends to accessories used to convert guns into what the government called “military-style” weapons.
