The Sisters form a stand-alone rock off Cape Brett. The rock splits in two to form a narrow canyon at 10m. On the seaward side of the canyon, the rock drops off to 40m or more to boulders, while the inland side goes to 30m. There can be strong current at this dive site.

The Nursery is a shallow dive site, with depths ranging from 5-20m. Juvenile fish are often found in this area. There are many cracks and boulders covered by colourful invertebrates and kelp.

The HMNZS Canterbury was decommissioned at the end of March 2005 and was scuttled on 3 November 2007 at Deep Water Cove in the Bay of Islands, making for a great artificial reef wreck dive.

Bird Rock is a large rock off Cape Brett. The walls of the rock slope down on all sides to 30-40m. In the winter, seals sometimes inhabit the rock and will jump into the water to swim with the divers. This site is recommended for more experienced divers as there can sometimes be strong currents.

A long finger extends from the land towards the sea. The finger starts at 12m and runs west down to 25m, where it drops further. Towards the deeper end of the finger there is a swim through. Further in towards the land there are big boulders and a small cavern.

Rocky kelpy reef in 10m of water on the inward side of the island leads out to 18-25m towards the seawards side as one circumnavigates the island. An underwater cavern is a main feature of this dive, approximately 5m wide at the entrance.
