Interesting this thread just popped up - I haven't had any fish for over a year, but have recently re-caught the buzz. I always wanted to check out the Reporoa guppy rumour, and today got the chance to jump in at two of the spots shown here. The records are from 1984 though... the streams I was in were nowhere near the 30oC recorded, and I only caught gambusia There is also a post in the forum that is a about 10 years old which mentions they were at Golden Springs... May get a chance to check out a couple of the other spots in the next week or two, but would be interested to know other peoples experiences
