About this tour
When Em from our BugBitten team booked this charter, we were diving the HMNZS Canterbury—a former Navy frigate now resting upright in Deep Water Cove near Cape Brett. It's a serious wreck for experienced divers, deliberately sunk as a training site and sitting in deep water that demands respect. The day involves two single-tank dives on gear that's provided, and you're working with a small group (max eight people). This isn't a casual reef potter; it's a proper technical undertaking that rewards divers who know their limits and their skills.
Highlights
- Intact Navy frigate resting upright—striking presence on the seabed
- Purposely sunk and maintained as a diver training destination
- Deep water location near Cape Brett with challenging conditions
- Two single-tank dives included with rental gear provided
- Small-group cap keeps the site from feeling crowded
- Requires current dive certification—no shortcuts for safety
- Medical vetting beforehand ensures everyone's genuinely fit to dive
What to expect
Em's dive day started with the health questionnaire and gear check—nothing glossy, just the essentials. The Canterbury sits deep, and the conditions demand focus: you're not cruising a shallow reef here. The wreck itself is the star: upright, intact, and genuinely impressive when you're descending toward it. Two dives means you get a proper look without rushing, though the deep water and potential current mean this isn't forgiving if your buoyancy control is rusty. The group stayed small, which helped.
You'll want solid experience before showing up. This isn't marketed as a beginner thrill; it's a wreck dive for people who've logged dives and know how to read the water. The charter sorts the dive plan with you beforehand, so there are no surprises about what you're getting into. Come in December–February for the steadiest conditions; winter swells can make the run out to Deep Water Cove choppy and the visibility patchy.

Good to know
If you're a qualified diver who's comfortable in deeper water and around wrecks, this is genuine—a proper training site that's been deliberately maintained, not a hastily scuttled hull. The gear hire takes the hassle out of transporting tanks and BCs, and two dives let you explore properly. The small group and mandatory medical checks mean you're diving with people who've been vetted. It's worth the cost and the travel for someone who genuinely wants to tick a Navy frigate off their list.
Deep water and wreck diving aren't casual. You need current advanced certification (or equivalent). You'll need to stay 48 hours post-flight before diving, which means planning a stopover if you're flying in. The site is weather-dependent—Deep Water Cove can get rough, and chop will kill visibility. Twin tanks and nitrox aren't included, so if you're after tech gear or mixed gas, that's extra. Pregnant travellers and anyone with cardiovascular concerns are ruled out. The drive to Cape Brett adds time and cost on top—transport isn't included.
Bring your certification card and medical paperwork. Contact the dive centre after booking for their info packs and to confirm the dive plan. Groups max out at eight people; technical tours run smaller. Book November–March for better water conditions. You'll need reasonable fitness—this isn't a wellness float. Expect to pay for fuel surcharge or charter costs separately.
