We're going to be in Rotorua for a few days in February. We plan to rent a car and then drive to Auckland to catch our flight back home. It seems that car rentals out of Rotorua are expensive compared to what what I've found for the South Island. Do rental companies offer free car rentals for relocations from Rotorua to Auckland or is the distance not long enough for that? Most of the relocations I've seen are for much longer distances. Thanks.
