Big issue is access, supplejack and bush lawyer do not make travel easy in places, only tracks are around the coast (ignoring the tin range and coming across the island from doughboy and masons)
No huts or tracks doesn't appeal to me personally but have heard of animals at the top of freshwater river catchment behind mt anglem and of someone who went off the rakiahua-doughboy track and found plenty of sign and animals of both reds and whitetail.
