I am flying to Auckland next month to tour NZ for 3 months, starting with N Island. I'm looking for info on how a fully-laden touring bike and rider (me!) would fare on the NZ cycle trail network, much of it offroad. I'd prefer to stay off road much of the time and wild camp (or freedom camp as you say in NZ).
I am pretty fit and an experienced tourer (I cycled around Australia 2007-08). The trails are graded from 1 to 5 I'm guessing that 1 and 2 will be OK for a tourer but 4 and 5 will be too hard. Although I'm not in a hurry to get anywhere.
How about Grade 3 trails, which many of them seem to be designated? Can anyone comment on how they would be for cycle touring?
