Could a beginner ride the Coppermine track in Nelson NZ?

I really want to take my wife on the Coppermine track in Nelson NZ but she really struggled on a grade 3 track in the Marlborough Sounds. You guys offered advice but to be honest it was very conflicting. So I decided to pre-ride the track and see exactly how hard the track is.
