Military style semi-automatics and assault rifles will be banned in New Zealand under stronger new gun laws announced today, Prime Minister Jacinda Ardern says.

'On March 15 our history changed forever. Now, our laws will too. We are announcing action today on behalf of all New Zealanders to strengthen our gun laws and make our country a safer place,” says Prime Minister Jacinda Ardern.

'Cabinet agreed to overhaul the law when it met on Monday, 72 hours after the horrific terrorism act in Christchurch. Now, six days after this attack, we are announcing a ban on all military style semi-automatics (MSSA) and assault rifles in New Zealand.

'Related parts used to convert these guns into MSSAs are also being banned, along with all high-capacity magazines.

'An amnesty will be put in place for weapons to be handed in, and Cabinet has directed officials to develop a buyback scheme. Further details will be announced on the buyback in due course.

'All semi-automatic weapons used during the terrorist attack on Friday 15 March will be banned.

'I strongly believe that the vast majority of legitimate gun owners in New Zealand will understand that these moves are in the national interest, and will take these changes in their stride.

'When Australia undertook similar reforms, their approach was to allow for exemptions for farmers upon application, including for pest control and animal welfare. We have taken similar action to identify the weapons legitimately required in those areas, and preclude them.

'Legislation to give effect to the ban will be introduced when Parliament sits in the first week of April. We will provide a short, sharp Select Committee process for feedback on the technical aspects of the changes. We are looking to progress the amendments to this legislation under urgency and expect these amendments to the Arms Act to be passed within the next session of Parliament,” says Jacinda.

'The Bill will include narrow exemptions for legitimate business use, which would include professional pest control. Police and the Defence Force will also have exemptions. Issues like access for mainstream international sporting competitions are also being worked through,” says Police Minister Stuart Nash.

'We have also acknowledged that some guns serve legitimate purposes in our farming communities, and have therefore set out exemptions for 0.22 calibre rifles and shotguns commonly used for duck hunting. These will have limitations around their capacity.

'While the legislation is being drafted, I am announcing the Government will take immediate action today to restrict the potential stock-piling of these guns and encourage people to continue to surrender their firearms.

Earlier this afternoon, an Order in Council under section 74A(c) of the Arms Act was signed by the Governor-General to reclassify a wider range of semi-automatic weapons under the Act. It came into effect at 3pm today.

'This interim measure will ensure that all of the weapons being banned under amendments to the Arms Act are now categorised as weapons requiring an E endorsement on a firearms licence.

'The effect of this is that it will prevent the sale of MSSAs and assault rifles to people with A category gun licences. The Order in Council is a transitional measure until the wider ban takes effect.

'We are introducing transitionary measures for gun owners to hand in their guns to Police to hold until details of a buy-back are announced. Likewise, the Police continue to accept guns for destruction.

'Again, we encourage gun owners to phone in to Police ahead of time to advise them they are bringing their guns in to the station,” says Stuart.

'The actions announced today are the first step of the Government's response. We will continue to develop stronger and more effective licensing rules, storage requirements and penalties for not complying with gun regulations. It is the Government's intention that these amendments will go through the full legislative process,” Jacinda Ardern said.

'To owners who have legitimate uses for their guns, I want to reiterate that the actions being announced today are not because of you, and are not directed at you. Our actions, on behalf of all New Zealanders, are directed at making sure this never happens again.”
