Boat-access artificial reef with easy outer sections and deeper routes
Access is normally arranged through a local Bay of Islands dive operator and suitable weather conditions.
HMNZS Canterbury (Wreck) is a boat-access artificial reef in Deep Water Cove, Bay of Islands. The scuttled frigate sits upright in a sheltered cove, with broad outer decks for training, a clear bridge-and-superstructure profile, and deeper interior routes for qualified wreck divers. Boat timing and calm settled weather matter more than current.
