Overview

Sea caves, stingrays and subtropical reefs off New Zealand's Tutukaka Coast

The Poor Knights Islands are an ancient volcanic archipelago turned marine reserve, sitting offshore from Tutukaka on New Zealand's North Island. Jacques Cousteau rated them among the world's top dive locations, and today they are famous for cathedral-like caverns, arches and walls coated in sponges and gorgonians, plus schools of blue maomao and visiting stingrays. Boats depart mainly from Tutukaka to reach this no-take, no-landing sanctuary, where divers, freedivers and snorkelers share clear water, dramatic topography and prolific subtropical life year round.

What Makes It Special

  • Iconic marine reserve

    Strict no-take, no-landing rules protect dense schools, invertebrate gardens, and subtropical visitors.

  • Caves, arches and walls

    Riko Riko Cave and arches like Blue Maomao and Northern Arch give photogenic caverns and light beams.

  • Subtropical wildlife

    Expect maomao schools, stingrays, kingfish, occasional dolphins or orca, and warm-current tropical visitors.

  • Freedive & snorkel friendly

    Nursery Cove and calm summer bays suit snorkel and freedive courses alongside deeper sites.

Best time to go

December to April

Longest days, warm air around 22°C to 24°C and sea temperatures near 20°C to 23°C, ideal for mixed diving and beach time.

Main caution: Cooler water near 14°C to 16°C and more frequent fronts. Often excellent underwater visibility but you need heavier exposure protection and more flexibility for wind and swell.
