Zorbing is great.  It's not something that you can really explain or try to compare to anything else, it's just fun.  You get done at the bottom, you're soaking wet, smiling, laughing, and wanting to do it again.  If you have any questions about things to do or see there, I've travelled throughout the country all tolled for over 7 months now.  It's a fantastic place to be.  For images, check out my website:  http://homepage.mac.com/jasonkearns/nz or email if you have any questions about things to do, places to stay, whathaveyou.

Enjoy!
