After many emails and lots of searching, we have opted for Pacific Auto Traders. They offer two different options. One is specifically for cruisers,$110 New Zealand dollars, picked up and dropped off at port with unlimited mileage. The other option is to Uber to their depot office, paying $59 New Zealand dollars, or $69 for intermediate, giving you 150 km’s a day. Uber runs $15 New Zealand dollars. If you want more km’s, it is $15. We are doing the Uber option. Hope this helps.
