Are you planning to cycle or hike your way around New Zealand totally unsupported? (without the aid of a support vehicle, public transport or transfers)

Arrive at any YHA hostel on foot or by bike, whether it’s 100kms or 1000kms away and you’ll be rewarded with up to 25% off the overnight rate per person per night.
I think this is a great initiative! I've stayed at a lot of hostels which recycle etc, but this is the first 'low carbon' initiative I've heard of.
