Scuba
What It Feels Like
Scuba at the Poor Knights is all about structure and life: sheer walls to 40 m, caverns like Riko Riko, arches packed with schooling maomao and pelagics cruising in from the blue. Local charters such as Dive! Tutukaka and Yukon Dive run daily trips from Tutukaka Marina, typically offering two different sites in a day and catering from confident Open Water divers through to experienced tech and photography teams.
Signature Sites
Start Here
Perhaps the most iconic Poor Knights image: a broad archway filled with hundreds of blue maomao backlit by turquoise water.
Middle Arch offers twin tunnels, kelp forests, dramatic contrasts of light and shade and regular encounters with demoiselles, wrasse and schooling snapper.
Advanced
One of the largest sea caves on the planet, Riko Riko offers a cavern style dive with a huge entrance, skylights, shafts of blue light and schools of maomao and sweep circling over boulder piles.
At the northern end of Tawhiti Rahi, Northern Arch is famous for summer stingray aggregations and vertical walls that drop into deep blue water.
Planning Playbook
Operator Checklist
- Most operators run full day trips with two dives, morning check in at Tutukaka Marina and {{ 60 | distance:minute }} to {{ 75 | distance:minute }} crossings to the islands depending on conditions. Summer and holiday periods can book out weeks ahead, so pre booking is essential. Ask in advance about nitrox, steel vs aluminium cylinders and whether you can bring twinsets or stages if you are tech trained.
- New Zealand law and operator policies typically require evidence of recent diving, so bring your logbook or digital logs. Prepare for live boat procedures: deploy an SMB, stay close to your guide, and listen carefully to briefings on surge, down currents and marine reserve rules.
