The New Zealand government introduced the Arms Amendment Bill Monday to reduce and restrict the number of semi-automatic and “military style” firearms, like the ones used by the recent Christchurch Mosque shooter.

The legislation bans the use of semi-automatic rifles including detachable parts including detachable magazines and pump-action shotguns that can hold more than five rounds that can be used to create much deadlier weapons. The bill does exempt farmers and hunters who could still hold rifles with more rounds. The loophole in current legislation allowed for Christchurch Mosque shooter to assemble his own weapon from semi-automatic weapons and high-capacity magazines that took the lives of 50 people.

The legislation also includes an amnesty period until September where the government will buy back these types of weapons to compensate owners who already own these rifles. The punishment for possessing one of these firearms after the amnesty period can range from an arrest to 10 years in jail.

If passed, the bill could go into effect as early as mid-April and would be one of the quickest government response to a national shooting.
