I've got one, 12 x 12 x 7x65R.
It's shot deer, but mainly it gets used as a shotgun with the capacity to shoot pigs or deer while hunting pheasants.
The rear sight folds into the rib and you flick it up when it's rifle time.
I like it. However they are expensive, not as light as a shotgun and not suitable for extended strings of rifle fire as the barrel bends as it is attached to the shotgun tubes so heat is lost unevenly. Still better than carrying two guns.
DOC (Taupo at least) have said that they won't prosecute if I use it on DOC managed land as long as I don't have shot cartridges on me - it is considered a rifle in that situation.
