About this tour
When Noah from our team booked this full-day scuba charter from Warkworth, he was after a shot at spotting juvenile hammerhead sharks migrating through the Hauraki Gulf. It's a proper deep-water experience — you're heading out to the outer islands where these pelagic visitors pass through on their way to the Pacific. The gulf itself has serious diving cred, and this charter banks on that. You'll get two tank dives, all gear sorted, and a boat ride out to the action. It's not a casual dip; this one demands real experience and a solid fitness level.
Highlights
- Pelagic hammerhead sharks moving through during migration season.
- Two full dives in a day from experienced local operators.
- Small groups — maximum 8 divers keeps it manageable.
- Outer-islands diving in a world-class gulf.
- All scuba kit and tanks provided and included.
- Option for less-experienced divers to hire a dedicated guide.
- Genuine pelagic encounter — not a guarantee, but the real deal.
What to expect
Noah headed out early from Warkworth to hit the charter boat while conditions were favourable. The boat ride to the outer islands took time, but the gulf itself is stunning — you're crossing properly open water where you see why this place has a reputation. Once at the dive site, the operation was tight: briefing, gearing up, and into the water for the first tank dive. The gulf can be a mixed bag — visibility and sea state shift with weather and season, so manage your expectations on that front. Between dives there's a surface interval where you catch your breath, review what you saw, and prep for dive number two. The hammerhead encounter isn't guaranteed (migration timing varies), but the reef and fish life around those islands is solid. The whole day is genuinely physical — you're not a passenger, you're working.
By the second dive, most divers settle into a rhythm. The boat crew handle logistics smoothly, and they know the gulf well. It's a full day out on the water, so bring tolerance for wind and spray. If you're not logging regularly, this will feel demanding.

Good to know
Experienced divers after serious pelagic action will find genuine value here. The Hauraki Gulf is a legitimate dive destination, and these operators clearly know it. Two tanks in a day keeps you engaged with the site rather than rushing. Small group size means you're not herded about. The option to hire a guide if you're rusty means less-experienced divers can still join mates without embarrassing themselves.
You need at least an open water cert and ideally 10+ logged dives — this isn't a resort course warm-up. Physical fitness is non-negotiable; if you're not regularly active or have any cardiovascular concerns, this won't work. Don't dive if you've flown in within 48 hours (decompression risk). Lunch isn't included, so bring food or accept a long day on minimal snacks. Weather can shut the whole thing down, and you'll need to reschedule. Pregnant travellers and those with serious medical conditions (asthma, heart issues) should consult a doctor first — there's a health declaration you'll complete. Transport to Warkworth is on you.
Bring a pre-breakfast meal, water, and seasickness tablets if you're prone. Expect 6–8 hours on the water including boat time. Maximum 8 people per booking. Medical cert required; book ahead so there's time to sort it.
