I really like Hawksburn Road which is very near the Nevis road that @oghood mentions above.
I also rate Black Forest Station but it does have some very steep rocky sections that may not be suitable 2 up on a big bike, the landscape however is awesome.
Just North of Danseys Pass is the Hakataramea Track pass which is a nice track.
I will be in Europe from early next year but probably won’t get to Italy until 2020.
