The Canterbury is my favourite wreck north of Auckland the depth and water quality make the visibility better than most other wrecks and more often than not you get a good 20m+ vis. Perfect for wreck penetrations if you’re qualified to do so but absolutely stunning even exploring the outside of the wreck.
We leave from Opua marina on the Whaakari Express to Deepwater Cove where the HMNZS Canterbury wreck sits. There are three moorings to choose from, the bow, midship, and stern. The boat trip takes around 45 minutes in good weather from Opua to Deepwater cove. Sometimes you will encounter dolphins and whales on the trip out and back in if you are lucky.
Sitting peacefully on the sand at 40m deep there isn’t much to typically see down at the hull of the ship. The bow has the shallower deck with lots of Jewel anemones and usually Maomao and Damsels. With the superb visibility, you can usually see the wheelhouse from the deck which naturally makes this section just look so cool. There you can head towards the midship up and over the wheelhouse or one of the open corridors where you can discover the tower that the midship mooring is attached to. This is the shallowest part of the dive and quite interesting to look around as you ascend. Near the stern, you will find the hanger and a nice large deck with lots of growth and sea life.
Dive Level Required
You definitely need your PADI Advanced Open Water or equivalent for this dive site just because there really isn’t anything worthwhile to see shallower than 18m. The most important speciality I would recommend would be doing an enriched air course because at this depth your NDL will probably run low before your air does. If you’re really serious about having a good time here I would have deep and wreck specialties paired with two cylinders in side-mount or get yourself a rebreather. It is so exciting being able to spend almost an hour penetrating and exploring the wreck on rebreathers with a buddy you know and trust.
Points of interest
The whole wreck is interesting from the hull to the mast and bow to stern, I have dived this wreck at least 15 times and even on the outside, I see something new and exciting. Popping your head into the wheelhouse I often see a resident kingfish and snapper that seem to be buddies cruising around together or down towards the stern, having a peek into the hanger is really cool too. For me going inside with a trusted buddy is what I love about this wreck, but I can not stress enough, there is serious danger when doing this even with the right skillset and equipment.
