hot pools One of the main attractions in Rotorua is the thermal waters long known to be excellent for people with creaky joints. There will be time for you to 'partake of the waters' if you wish.
Another activity is a visit to the Agrodome, a very successful ( and humourous  ) showpiece for New Zealand agriculture..a very entertaining hours show.
