The second tranche of proposed gun law changes has been announced which will include a firearms register and a tighter licencing system.

The next Arms Amendment Bill - following the ban on military-style semi-automatic weapons and assault rifles - will include establishing a firearms register and requiring licences to be renewed every five years.

It will also "enshrine in law that owning a firearm is a privilege and comes with an obligation to demonstrate a high level of safety and responsibility".

Prime Minister Jacinda Ardern made the announcement alongside Police Minister Stuart Nash on Monday. It's the second set of gun law changes following the terror attack on 15 March.

"The changes announced today have been decades in the making. It is now up to this Parliament to deliver in the interests of public and personal safety," Ardern said.

Nash said the vast majority of our gun owners are law-abiding and responsible, but emphasised that owning a gun is a "privilege, not a right".

"The law changes will reinforce the positive behaviour that is required of all gun owners," he said.

The legislation is being drafted and is due for introduction in late August. It will spend three months at select committee for public feedback.

The second tranche of legislation will include:

Establishing a firearms register

Make owning a gun a "privilege" that comes with obligations

Tighten the rules to obtain and keep a gun licence

Tighten the rules for gun dealers to get and keep a licence

Require licences to be renewed every five years
