As part of our trip through New Zealand, my guidebook mentioned Poor Knights Islands as some of the best sub tropical diving in the world (and especially New Zealand], so we took 3 days to go dive there with Ocean Blue Adventures. It's a small liveaboard, but they were nice enough to give us the one room (they had some bunks for the rest of the folks), and it was comfortable enough for that duration. The crew of 2 did everything they could to make the trip and diving as nice as possible.
Poor Knights Island is a 2H boat trip from Tutukaka, so it was nice to be able to stay on site and do more dives than the other boats that only did 2 dives per day.
Water was on the cold side (19 to 22C). Jennifer got too cold on her first day due to not putting 2 wetsuits on right away (ideally one would have been enough, but her body just gets colder than mine and then needed more time to recover). She missed a few dives as a result, but enjoyed the ones she did. I did all the dives myself, although 19-21C with a 7mm suit was really on the cold side.
The diving was interesting. There were scorpionfish everywhere, as well as nice nudibranch (some quite fat), and even nudibranch on top of scorpionfish (that was weird):
I totally missed the scorpionfish underneath when I took the picture
There were loads of rays too:
Loads of moray eels of all kinds:
nice blue moray eel
that poor fish had a tumor
We did one night dive. Lots of little food floating around :)
And that was the conclusion of our 3 days of diving at Poor Knights Islands. It was cold, pretty tough for Jennifer and borderline for me, but it was interesting to see different critters from what we usually see during tropical diving
