How wide is the rail corridor through both Islands? Isnt it something like 15mtrs? And as teh gubbermiint owns it, should be the starting point (IMO). It has numerous pitfalls, but essentially covers the distance at an acceptable gradient and is in state hands already.
Why start from scratch? Using the existing rail corridor we could have this 80% done in 24 months (still have issues around tunnels and major cities etc in that 20%). Any community wanting to take advantage could link to that line, giving people the choice to ride the rail line, or past their community. Given the choice, some will straightline, some would detour for some singletrack and a coffee/accomodation etc.


perhaps they could route the NZ one through the craters of the moon then over Huka falls and on to the redwoods, it coyld take in the 42nd traverse then down to Welly via upper hut and the Karapoti. over the nelson trails and down the inner kaikoras probably twisting through Hamner ond on to the port hills and south. they could save a lot of money by utalising the existing trail network
