We took Jim's day tour as we were on a New Zealand, Australia, and Bail Cruise. We met Jim outside the port gate, where he greeted us with a big smile and sign with our names on it.
Jim's knowledge of the geothermal sites and history New Zealand is extensive. We loved listening to him and enjoyed his company for the day. We never felt rushed on his tour and we got back to the pier in plenty of time to board our ship.
We would highly recommend this tour.
My advice is book his tour early.
