Just wanted to share this website :
http://nzopengps.org/.
This is a free Community Garmin GPS map of New Zealand. It is really GOOD! It gets updated within 24-48 hours of a report error. It beats those commercially available maps (ie. New Zealand City Navigator). I have tested it - lots of Point of Interest and Turn-by-turn Routing works too.
I am breathless. Did I say it was free too??
