Te Papa in Wellington has the colourful Split Enz suits on display if you want to check that out. If you're a sporting fan there's the Cricket museum in Wellington and the Rugby museum near Auckland i think. Staglands in Wellington (Near a place called Upper Hutt) is one place worth checking out, it's like a petting zoo but it's amazing, it really brings out the fun in people. Stewart Island is really amazing, it's one of the most beautiful places i've ever seen and it's so peacful and wonderful. Enjoy your stay here in NZ and i hope it gives you many wonderful memories.
