Picked up the car at Auckland International Airport. The car had just over 50,000 kilometers on it, a diesel Toyota Prado, which I drove all the way to Wellington. There are two ferry companies for crossing to the South Island, we chose Bluebridge Ferry, whose departure point is near the train station in the city center, which made returning the car inconvenient. The return point was at the other ferry company, so we had to unload our luggage first and then return the car. There was no staff at the return location, so we just dropped the key in the key box. After the ferry ride, we picked up the second car, another Prado, at the Picton pickup point. This one was newer, with only 10,000 kilometers on it. The diesel Prado was really great. We drove for a total of 19 days without any issues. Finally, we returned the car at Christchurch Airport, where the office was staffed. They just checked if the fuel was full, and that was it.
