HMNZS Canterbury Stern

January 17, 2020

The first morning of diving we took the boat out to Deep Water Cove to dive the HMNZS Canterbury. The HMNZS Canterbury (F421) was one of two broad beam Leander-class frigates operated by the Royal New Zealand Navy (RNZN) from 1971 to 2005. She was decommissioned in 2005 and enthusiasts at the Bay of Islands Canterbury Charitable Trust proposed the idea of scuttling her as a dive wreck at Deep Water Cove in the Bay of Islands. The ship itself had been sold to the trust for a symbolic NZ$ 1.

The Canterbury is 114 m long so it's effectively impossible to dive the deck of the entire ship in one dive.

For this dive we were moored mid-ship and descended to explore the stern.

At the stern is a helicopter landing pad and bay for the helicopter itself. It was dark inside but easy ingress/egress for the bay so we ventured inside.

Not so much to see in the dark but in the back right corner was what appeared to be an electical room.

The remainder of the dive down to the stern was teeming with life.

Exploring the Canterbury

At one point I found a fish cleaning station where fish were grinding themselves against the rusty metal of the hull.

At the end of the dive we ascended up one of the towers and were surrounded by a school of fish during our 3 minute safety stop.

To top it off it was a very short trip to Deep Water Cove where we spent our surface interval, had lunch, and relaxed in the sun.
