Should have looked at your handle first and seen that you were from Bathurst
so you are definitely in the know!
Anyway back to NZ.
Flew into Christchruch and drove to Queenstown.

Wanaka to Makarora
Makarora to Hasst
Haast to Fox Glacier
Fox Glacier to Frans Joseph Glacier
Frans Joseph to Hokitika
Hokitika to Grey Mouth
Grey Mouth to Reefton
Reefton to Mauri Springs (spelt different and dont go there if you can help it)
Mauri Springs to Hanmer Springs
Hanmer Springs to Christchurch
All in all was about 1100km so not that big a ride really. We had a few people in the group of varying degrees of fitness so we had to make some of the distances a bit smaller than you normally would. But probably averaged about 60 to 70 km a day. I thought that it was a good route but we missed out seeing a few places that i would have liked (ex: Nelson, Able Tasmain national park, Milford Sound).
Can give you more specifics about things/places if you like, just let us know.
