I had an endorsed licence for 27 years and had a number of rifles, machine guns and pistols on that licence, I had/have a strong room, wireless alarm and two dogs that dont like strangers. My security is/was top notch. I have been through 2 lots of vetting, and my background and who I associate with has been reviewed in depth. I have also worked as an advisor to Police for the past 5 years on appointment by members of the Law & Order Select Committee. I also worked on the team that priced all the firearms for buyback and am a registered police valuer and range inspector. I can tell you Police management of the Arms act is very poor. When road policing stats look bad the district commanders raid the Arms budget so they can try and bump up the road statistics. Arms Officers are overworked and vetting officers are paid a pittance.
An incident like Christchurch was a tragedy, but if Tarrant didn't have a licence this would not have happened. He had no underworld connections to get guns so he would have really struggled to find what he wanted. Police were slack at Aramoana, they did not follow up when the Napier Gunman lost his licence and one of their own was killed as a consequence and they have failed to deal with gangs and guns. Saying that MSSA firearms are a bad look for Gun owners is a joke, it's like saying high performance cars are bad look for SUV drivers.
I sold back well over $150k worth of WW2 collectible firearms in the buyback, the Govt trampled over democratic process and vilified firearms owners so they could promote the buyback (Paid confiscation). They banned ammunition that is far less lethal than many readily available hunting rounds and refused to pay for it, worse still they could not even clearly define what was actually banned. They worked on appearance and hyperbole rather than fact and rushed it so no once could argue. They are typical socialists who hate firearms on principle and I can tell you that some of the regulations (not subject to democratic process) are draconian, have been dreamed up by people who have no idea what they are doing and are totally ineffective.
What you should worry about is when they turn their eye towards vehicles especial if there is a Labour/Green coalition. You can bet a tax on the type of cars we like will be in there somewhere and dont bet that they wont ban some things outright.
