The police buy-back for now-illegal firearms ends at midnight on Friday, and with less than a day to go about 50,000 guns have been handed in.
Hamish Bruce is one of the gunsmiths approved by police to modify guns so they comply with the law - he speaks to Susie Ferguson from Ashburton.
Police didn't want to be interviewed about the buyback today but said every police district has at least one collection event open until 8pm on Friday and guns can also be surrendered at police stations.
