Tawharanui - Poor Knights Islands
Tawharanui sits in a sheltered corner of the Poor Knights, making it an easy drift for newer divers. We’ve found it’s a good spot to get your bearings, usually calm enough to just relax and watch the reef go by. You’ll often see schools of demoiselles flickering around the kelp, and if you keep your eyes peeled along the reef wall, there are usually nudibranchs tucked away. It’s pretty shallow, topping out at 12 metres, so it’s a perfect spot for extending your bottom time and just soaking it all in.
