Thread: manufacturer of a firearm is it legal in nz

i wish to make a gun i am designing and wondering if it is legal or do i need some type of permit i have a standard A cat gun licence and if it was made to A cat specifications do i need anything else then that.

P.S
at the moment this is theoretical. would have to find out if it would work and it would only be using 22lr ammo at least to start out to see if it would work if it made it past the drawing board
