This city is situated on the shore of Lake Rotorua, it is a very scenic location and you can hire kayaks and small boats and cruise the lake or you can do the cruise in style on the big paddle steamer cruise boat.
The only down side to Rotorua is the smell. As it is located in an active thermal area, the smell of rotten eggs from all the sulphur in the air is quite unpleasant. You will notice it as you arrive in the city but you do get used to it after a while.
