NO REPORTER NARRATION It was the first of 258 events that will be held over the next three months to compensate owners of powerful but newly banned semi-automatic weapons prohibited in the wake of deadly attacks on two mosques in Christchurch.
Police said a total of NZ $433,682 ($290,133) was compensated to gun owners on Saturday and the New Zealand government has previously said NZ $208 million ($139.15 million) has been set aside for the scheme.
The buy-back takes place four months after New Zealand's worst-ever peacetime mass shooting in which 51 people were killed and dozens injured in attacks on two mosques in Christchurch.
Parliament passed the gun reform law - the first substantial changes to the country's gun laws in decades - by a vote of 119 to 1 in April.
The new laws bar the circulation and use of most semi-automatic firearms, parts that convert firearms into semi-automatic firearms, magazines over a certain capacity and some shotguns.
With a population of just under 5 million, New Zealand is home to an estimated total of 1.5 million firearms, making it the country with the 17th highest rate of civilian firearm ownership in the world, according to the Small Arms Survey.
