"It's important that we get these firearms off the street and out of the wrong hands," she said
Police figures show nearly 14,000 people hold firearm licences in the Northland police district. But there is no way of knowing how many guns are in circulation.
About 40 firearms were reported stolen in Northland in the last fiscal year to the end of June 2014. They included BB guns, air rifles, shotguns and high-powered rifles.
In some of the burglaries the firearms were targeted and in other burglaries they were taken among other items.
In a July burglary thieves smashed their way into a locked gun cabinet in a house at Kauri and stole a .22 rifle and a .45 lever-action gun, and some boxes of .45, .22 and 9mm ammunition.
In June a 12-gauge shotgun and a camouflaged semi-automatic 12-gauge shotgun were stolen during a burglary of a Dargaville home.
Stolen firearms are also regularly uncovered by police when they carry out drug busts in the region.
