We will be picking up a hire car in Auckland (city or north shore) and after 2 weeks touring, dropping it off in the Bay of Islands (preferably Paihia). There don’t appear to be any agencies in Paihia who offer one way from Auckland and for Auckland based rentals hefty one way or pick up charges from Paihia apply. Returning the car to Kerikeri and getting a bus/taxi back to Paihia seems an option. Your view (and car hire company recommendations) would be appreciated. Thank you.
