Quoting fussy
they do not sting for one way trips
Not in my experience - me and my girlfriend hired a juicy camper and drove from Queenstown to Auckland via the Picton -Wellington ferry. They charged us a 'relocation fee'.
Take a close look at the T&C's - I know they are boring but there are some additional costs that you may have not budgeted for such as the 'Diesel Road User Tax' (although I think you can waive this by paying on top of your insurance.
Dont get me wrong the camper was excellent and served us well - there were a few extra surprises when we went to pick it up.
The ferry was a little expensive but I do believe the trips are cheaper somedays than others so you can plan your trip to suit - for more info go to www.interislander.co.nz
Have a great time!
