With the demise of the other sites listing good roads in New Zealand I have decided to try document them myself.
This will probably lack some local knowledge however I have ridden there 3 times and also driven around the country and have covered a good portion of the roads listed in the now out of print New Zealand Motorcycle Atlas. I have traced all the roads I have traveled that I know to be good onto this map and then added another 30% that I know of but have not ridden personally yet.
I have not added descriptions yet, I think it is a good start and will work to get the road names improved and perhaps add more info later, you can view the roads using street view anyway to get an idea but most riding in NZ is flowing roads with light traffic and very enjoyable.
