Thread: Firearms over all length current legislation

Can anyone put up a link to the current legal description of A Cat firearms over all length ?

I know it's 30" 762mm
But specifically want to part about continuous bore or rifling
Or if it has been amended to inclusive of permenantly attached muzzle devices included

I personally find the NZ Police web site pretty hard to navigate
Sometimes the search engine doesn't find certain forms even when I have the exact same one in my hands

Anyone who can help in sending me to the exact spot to read the current version much appreciated

Cheers
