Prime Minister Jacinda Ardern says New Zealand will ban all types of semi-automatic weapons and assault rifles following the Christchurch gun killings.
Also, an amnesty has been imposed so the owners of affected weapons can hand them in, and a buy-back scheme will follow.
The announcement comes less than a week after fifty people were killed at two mosques, allegedly by a lone gunman.
Ms. Ardern said she expected new legislation to be in place by April 11, saying: “Our history changed forever. Now, our laws will too.”
All of the dead have now been formally identified, police have confirmed.
Australian national Brenton Tarrant, a self-professed white supremacist, has been charged with one murder and was expected to face further charges.
But police said on Thursday that the person he was formally accused of killing had been wrongly declared dead.
They said they had apologised to the woman and her family, and that the charge sheet would be updated when the suspect appeared in court on April 5.
