Tahi Nui - Moorea & Tahiti

Waiwiri Rock is one of those places that feels like a lucky dip, even if we know what’s generally around. This isn't a deep dive, mostly hovering around the 15-20m mark, but it’s packed. The entire site is essentially a series of massive boulders and smaller rocks, which means plenty of nooks and crannies. We’ve seen enormous schools of trevally here, swirling so tightly they almost black out the sun, and the vibrant blue maomao add a constant flash of colour. It’s the sort of dive where you keep your eyes peeled for something bigger cruising by, with bronze whalers and even hammerheads making appearances, especially in summer. Our favourite time to hit Waiwiri is on an incoming tide. The visibility often bumps up a few metres, and everything seems a bit more active. You’ll find New Zealand scaly-headed triplefins perched on the rocks, and those little crimson cleaner fish are always busy. It’s a great site for divers who appreciate the thrill of the unexpected and enjoy spending time exploring rocky terrain.
