We are a Cook Islands–based NGO dedicated to catalyzing marine regeneration across our islands

Inspired by the wisdom of our Tupuna (ancestors), we work alongside our largest and smallest island communities, traditional leaders, scientists, and youth, to restore and protect the ocean ecosystems that sustain our people and way of life.

Through reef restoration, knowledge sharing, and community-led stewardship, Ocean Tupuna supports a future where the Moana thrives, both today, and for many generations to come.

Our Sister Initiatives

Ocean Tupuna works alongside its sister initiatives, each nurturing a different relationship between our people and the ocean.

Ocean Toa is a responsible turtle tour initiative in the Cook Islands that provides respectful encounters with sea turtles while ensuring activities protect marine life and contribute directly back to ocean conservation and community regeneration efforts.

Ocean Ancestors
Ocean Ancestors is an international partner supporting the revival and sharing of ancestral ocean knowledge, helping connect Indigenous wisdom and modern science to strengthen marine stewardship across communities.

Ocean Tamariki
Ocean Tamariki is a youth-focused initiative that inspires and educates children about marine ecosystems, nurturing the next generation of ocean guardians through hands-on learning and connection to the moana.
