Yeh these guys are high fenced, I know what you mean though I've done a bit of hunting in NZ and have seen things over there. Quite often the free range deer are just high fenced stuff released, true NZ wild deer are generally quite poor, a 35" 12 pt stag is a very big deer, the norm is more around 8 and 10 pt 30" heads.
All my personal hunting is free range but it's very hard and the success rate just wouldn't be high enough for me to run guided hunts on there at this stage.
If you're interested in seeing the quality of free range stuff in australia, I posted up a thread in the exotics section a few weeks ago about red deer with some free range stuff myself and my brother have taken.
I prefer meat in it's original packaging.
