Christchurch is located on the south island, so it takes a short flight to get to see the north island. The thirds sampling trip was on the north island and I took the weekend before the sampling trip to discover Auckland. The first day I of this weekend I went to see a national park west of Auckland. In this national park are two canyons, which are big (and safe!) enough to be ventured through.
Although I have never done a trip like that before, I am quite comfortable in a harness and especially in a wetsuit, but I had never combined the two. The result was great! The first effort was getting the equipment to the top, which definitely cost me some sweat, but abseils, dives, jumps and climbs easily made up for it!
