My wife and I will be taking a one month visit to NZ in February, 2012. She doesn't ride a bike so it will be by car, likely seeing as many of the "highlights" of NZ as possible in a month.
After she leaves, I can spend another month riding my bike around.
Would it be better to go to Tasmania, a place I haven't ever been to, or to spend more time in NZ's South Island probably riding a bike through places I recently drove through?
I realize this is a hard question to answer for someone else. I was just wondering of the relative merits of South Island NZ versus Tasmania for bike touring in March.
