New Zealand applied stricter gun lows three months after the incident Licensed gun owners have six months to surrender newly outlawed weapons WELLINGTON: New Zealand opened a gun buyback scheme Thursday aimed at ridding the country of semi-automatic weapons similar to those used in the Christchurch mosque attacks that killed 51 Muslim worshippers. Prime Minister Jacinda Ardern vowed in the hours after the March 15 killings that New Zealand’s gun laws would be tightened and her government has expedited the change in just three months. “The buyback and amnesty has one objective — to remove the most dangerous weapons from circulation following the loss of life at Al-Noor and Linwood mosques,” Police Minister Stuart Nash said. The Australian man accused of the killings, Brenton Tarrant, is alleged to have used an arsenal of five weapons, including two military style semi-automatic rifles (MSSAs), in the attacks on two Christchurch mosques. Lawmakers voted to outlaw MSSAs, which allow the rapid fire of high-calibre bullets, by a margin of 119-1 in the wake of the worst massacre in modern New Zealand history. Licensed firearms owners will have six months to surrender weapons that have now been deemed illegal under the scheme, with an amnesty ensuring they will not face prosecution during that period. After the amnesty expires, possession of a prohibited firearms is punishable by up to five years in jail. Compensation will be based on the model and condition of the firearm, with the total cost of the scheme estimated at $143 million. That includes $11.9 million toward administration costs for what Nash said was “a huge logistical exercise.” He said police knew of 14,300 registered MSSA rifles and there were an estimated 1.2 million firearms in the community, with the vast majority still legal under the new rules. Police said they were organizing “collection events” around the country where firearms owners could submit their weapons. Tarrant last week pleaded not guilty to terrorism charges, as well as 51 counts of murder and 40 of attempted murder. He was committed to stand trial in May next year.
