Queenstown it's down the South Island big destination for tourists also good for skiing or snowboarding depending on what time of year you are comming.
There are lodges up and down the country plenty of hunting and fishing here the South Island is the most scenic and well worth spending a bit of time in.
I've been salmon fishing once and it was pretty cool we smoked it and ate it the next night with some red wine in front of the fire very nice.
