dennisr - follow the link above. They are a bloody awesome map set and in most countries would be worth $$$$. There is a couple of interesting things I have come across where roads don't link up but then again I like to ride gravel and we don't want the the auto routing sending people between Chch and NN via the Rainbow (as happened to an ausi couple).
Also they are updated every so often so it is worth downloading the latest map set every other month.
Cheers R
