Further to my last comment, i have now found out they do have 13 brand new private pools i had a look on their website and they look very lush! even more reason to revisit. I would highly recommend the hot pools to anyone visiting rotorua from NZ or abroad! They are the best hot pools in the north island if not NZ!
