Looks like a fun climb to boot - http://www.backpackingmatt.com/climbing-mitre-peak-new-zealand/
+1 on the cruise out to the Tasman Sea, one of the few times its actually fun to play tourist for a day. My friend and I ran into a guy on the ship who worked for the cruise company. He had a faint NZ accent at first, we found out he went to Lynchburg in Virginia and his accent all of a sudden seemed to fade away. You can also kayak out there as well and I agree with Scott P thats its just as spectacular on a foggy, rainy day. Eerie, beautiful landscape down there. Sheep, Asians, unnecesarily extreme sports and mind bending vistas is what New Zealand is all about.
