Poor Knights Islands
Jacques Cousteau ranked these volcanic sea stacks among the world's ten finest dives.
The water clears to thirty metres as the boat anchors off the volcanic sea stacks. Below the surface, Poor Knights Islands drop through arches, caves, and kelp forests into a deep-water world that Jacques Cousteau ranked among the planet's finest dives.
The Poor Knights are two main islands and several rock stacks located twenty-three kilometres off Northland's east coast. A rāhui placed by Ngāti Wai after a devastating raid in the 1820s means no human has lived here since. The surrounding marine reserve, established in 1981, has allowed fish populations to recover to extraordinary density. Subtropical species from the Coral Sea appear here at their southern limit — nudibranchs, subtropical wrasses, and mosaic moray eels. The underwater arches at Northern Arch are large enough to swim through in formation.
Solo
Dive operators run trips from Tutukaka that cater to solo travellers. The dive briefing creates instant community, and the underwater experience is profoundly solitary.
Couple
Snorkelling the shallow bays requires no certification and reveals enough marine life to fill a conversation for days.
Friends
A group dive through Northern Arch — swimming through the volcanic tunnel together — is the kind of shared experience that becomes a permanent reference point.
- Underwater arches and caves descend through volcanic rock into water with thirty-metre visibility.
- The islands have been uninhabited since a Ngāti Wai rāhui was placed after a massacre in the 1820s.
- Subtropical fish species from the Coral Sea appear here — the only place in New Zealand they're found.
- Night dives reveal bioluminescent plankton and the rare cave-dwelling dactylanthus parasite flower.
