Twenty-three Cook Islanders, primarily youth from across a range of sectors, took part in the China–Cook Islands Training Program on Deep-Sea Resource Management, held in China from 24 August to 2 September 2026.
Representing the National Environment Service (NES) were Keanu Harawira, Environmental Compliance Officer, and Maria Maoate, Research & Data Coordinator.
The programme was organised by the Cook Islands Seabed Minerals Authority (SBMA) and the Second Institute of Oceanography (SIO), Ministry of Natural Resources, China, with training delivered in Hangzhou and Changsha.
Over the 10-day programme, participants followed the pathway of deep-sea mineral development – from how resources are formed, explored and assessed, through to environmental studies and impact assessments, mining technology, mineral processing, economics and governance.
A particular focus was polymetallic nodules, the type of deep-sea mineral resource found within the Cook Islands. Cook Islands nodules have relatively high levels of cobalt compared with nodules found in other parts of the world, influenced by the unique conditions of our deep-sea environment. Participants learned how seabed resources are mapped, sampled and assessed, and how geological and environmental information is collected from the deep sea.
For NES, the training provided valuable insight into the environmental considerations associated with potential future seabed mineral activities. It reinforced the importance of a precautionary and science-based approach, supported by strong environmental and biodiversity baseline information, environmental assessment and ongoing monitoring.
Beyond the classroom, visits to scientific research institutes and marine technology facilities provided practical exposure to underwater surveying and monitoring technologies.
The experience highlighted the importance of NES remaining engaged as knowledge and technology continue to develop, while strengthening local capability in environmental assessment, monitoring, compliance and environmental data management.
More broadly, the programme strengthened the capacity of Cook Islanders, particularly young participants, to engage in future discussions and decision-making around deep-sea resource management. It also strengthened relationships within the Cook Islands delegation and with Chinese scientific and technical institutions, supporting future information exchange, training and research collaboration.
