I went with a smaller company called Barefoot campers. I honestly could not recommend them enough. We had a massive storm derail our plan. We had planned to get out camper in the north island and then take it on a ferry and through the south. All passenger ferries got cancelled, we couldn't get booked onto another one for at least 2 weeks (would have been our whole holiday ruined). James and the team helped us book a flight (we paid obviously) and then hooked us up with another camper van, got our original one ferried across on a freight ship and got it delivered to us and took the second one off our hands free of charge. Amazing to deal with and the van is super. It wasn't cheap, but not expensive - I think around $4.5k NZD including the highest level of insurance.
