Pros: Naia was a friendly and informed guide. It's a very reasonably priced tour for the gear provided. The water is very still.
Cons: I went at the beginning of September and it was still much too cold to fully enjoy (this probably would have been a 4/5 if the water was warmer). The water wasn't cloudy, but it also wasn't as clear as I was expecting. I saw a lot of big snapper and teeny jellyfish and that was very cool, but I didn't see as many different animals as I was expecting.
Takeaway: I would recommend this in later spring or summer if you're trying to stay close to Auckland, are on a budget, want a guided tour, and want to use proper scuba gear.
