New Zealanders have handed over more than 10,000 guns, weapons parts and accessories in the first week of a buy-back scheme prompted by the country’s worst peacetime mass shooting, police figures released on Sunday show. A gun reform law passed in April banned most semi-automatic firearms, parts that convert firearms into semi-automatics, magazines over a certain capacity and some shotguns. Owners have until Dec 20 to hand in their weapons and the government has set aside NZ$208 million ($140.63 million) to compensate them for up to 95% of the original cost. The buy-back comes four months after a lone gunman with semi-automatic weapons attacked Muslims attending Friday prayers in Christchurch on New Zealand’s South Island, killing 51 people. More than 2,000 people have surrendered 3,275 firearms, 7,827 parts and accessories and in return authorities have paid them slightly more than NZ$6 million ($4.06 million) since the buy-back began last Saturday, a police spokesperson told Reuters by telephone yesterday.
