The Sisters. Now this is a proper Bay of Islands classic, a standalone rock that just screams "dive me". We love the way it splits into that narrow canyon around 10 metres, it's like a secret passage. Drift through there if the current allows, and it often does, the flow really brings in the action. We've seen schools of stripy and spotty so thick they’re a shimmering wall, and the black cod here are just magnificent, big and bold. On the seaward side, the drop-off disappears into the depths, but we usually stick to that inland slope down to 30m, poking around the boulders for nudibranchs like the Clown and Febelina. Keep an eye out for kingfish cruising past, especially in summer. Visibility can swing, but we've had some cracking 15m days here, making it perfect for divers who enjoy a bit of current and a lot of fish.
