Protecting Our Moana: Patukeha's Response to Caulerpa

The invasive seaweed Caulerpa poses a serious threat to the moana of Īpīpiri, smothering kaimoana beds, damaging marine ecosystems, and undermining the traditional practices and livelihoods of our people.

As kaitiaki, Patukeha has taken responsibility for leading local action - coordinating marine surveillance, rāhui enforcement, community education, and on-the-water monitoring to contain and manage the spread of Caulerpa. Drawing on local knowledge, practical experience, and a deep connection to place, our focus is on taking meaningful steps to protect the health of the moana.

Patukeha teams have been active in identifying infestations, coordinating removal trials, engaging with local boaties and divers, and supporting the roll-out of biosecurity measures and signage across the Bay of Islands. Our kaitiaki are also advocating for stronger government action, consistent long-term funding, and clear management planning to safeguard our moana beyond short-term interventions.

This kaupapa is supported through funding from the Ministry for Primary Industries (MPI), Biosecurity New Zealand, and the Northland Regional Council, with additional resources being sought to expand community-led restoration, monitoring, and education initiatives.

While the challenges are significant, the work continues. With sustained effort, collaboration, and care for our marine environment, there is hope that the moana will recover — and that future generations will inherit waters that are once again vibrant, resilient, and full of life.
