Nearly 50 New Zealand Defence Force personnel have completed six weeks of infrastructure improvements, healthcare services and maritime surveying on one of the Cook Islands’ most remote atolls, strengthening ties between Aotearoa and its Pacific neighbours.
The deployment to Penrhyn, also known as Tongareva, nearly 1,400 kilometres north of Rarotonga, formed part of Exercise Tropic Twilight, an annual New Zealand-led humanitarian assistance and disaster relief programme.
Running from early September to mid-October, the operation brought together New Zealand Army engineers, medical and dental specialists, Royal New Zealand Navy hydrographers and personnel from Vanuatu and French Polynesia.
The exercise delivered practical improvements to community facilities while strengthening local resilience and relationships across the Pacific.
Building Infrastructure for Remote Communities
New Zealand Army engineers from 25 Engineer Support Squadron and 2 Engineer Regiment completed a range of construction and maintenance projects designed to improve essential services on Tongareva.
At the Omoka Cyclone Centre, personnel constructed a new laundry facility, while Omoka School received a new shelter, improved water infrastructure, repairs to stairs and decking, upgraded toilet facilities and a new life-skills classroom.
Five solar stills were also installed, electrical improvements were completed at Te Tautua School, and additional water tanks were provided to increase rainwater collection capacity at community buildings.
These improvements are particularly important for remote Pacific communities, where access to construction materials, specialist tradespeople and reliable infrastructure can be limited.
With climate-related hazards and extreme weather presenting ongoing challenges across the Pacific, improvements to water security, schools and cyclone facilities can also strengthen community preparedness.
Healthcare Delivered Directly to Islanders
The deployment included nine medical and dental personnel who worked alongside local healthcare providers to deliver essential services.
Almost 60 dental patients received treatment during 17 days of clinics, providing access to care that can be difficult to obtain in isolated island communities.
Health personnel also conducted medical checks, medication reviews and follow-up appointments for residents managing ongoing health conditions.
The work provided additional support to local health services while helping address immediate healthcare needs.
Navy Maps Previously Uncharted Hazards
Eight Royal New Zealand Navy hydrography personnel undertook detailed surveys of Penrhyn’s navigational approaches, lagoon transit routes and other important maritime areas.
Using sonar technology, the team gathered information about the seafloor and identified previously uncharted hazards.
The resulting data will be provided to the Cook Islands Government to support safer navigation and future maritime planning.
For an isolated atoll heavily dependent on marine transport, accurate navigational information is an important part of maintaining reliable access to essential supplies and services.
Pacific Nations Working Together
Exercise Tropic Twilight also involved personnel from the Vanuatu Mobile Force and Les Forces armées en Polynésie française, highlighting the importance of regional cooperation.
The programme is led by the NZDF and funded by the Ministry of Foreign Affairs and Trade, with projects agreed between the two organisations.
NZDF Youth Development Unit personnel also supported a Blue Light youth development programme in Aitutaki as part of the wider exercise.
Detachment Commander Major Cam Gurney says the deployment was designed to strengthen New Zealand’s partnership with the Cook Islands while contributing to Pacific resilience.
He says the friendships developed with the people of Tongareva were just as important as the infrastructure and services delivered.
NZDF personnel were welcomed into local homes, churches, workplaces and community activities throughout the deployment.
The strong hospitality and relationships developed over the six weeks became a defining feature of the exercise.
Tongareva Community Welcomes Support
Penrhyn Mayor Rangi Taia expressed the community’s appreciation for the work completed and the relationships formed between residents and visiting personnel.
The mayor acknowledged both the practical improvements delivered and the kindness shown by the NZDF team during its time on the atoll.
Major Gurney also recognised the significant contribution made by local residents, who worked alongside personnel on construction projects and provided support behind the scenes.
The cooperation demonstrated the importance of partnerships that involve local communities directly in planning and delivering improvements.
Massive Logistics Operation Behind the Mission
Delivering the programme to such a remote location required extensive preparation and logistical coordination.
Construction materials were transported by barge, while specialist equipment, personnel and priority supplies were flown in by the Royal New Zealand Air Force.
NZDF logisticians coordinated the delivery of approximately:
- 20,000 litres of drinking water.
- 2,000 ration packs.
- 10,000 litres of diesel.
- 160 cubic metres of freight.
- Thousands of construction materials and specialist items.
At the conclusion of the exercise, tools and construction materials were donated to the Penrhyn community for future projects.
Surplus drinking water and ration packs were also left behind to support local needs.
Strengthening Pacific Resilience
The deployment reflects New Zealand’s ongoing defence and humanitarian relationships with Pacific nations, particularly communities facing challenges associated with geographic isolation, infrastructure needs and disaster preparedness.
For Aotearoa and its Pacific neighbours, programmes such as Tropic Twilight demonstrate how cooperation can deliver tangible benefits beyond traditional military activities.
The improvements to schools, water systems, healthcare and maritime navigation will continue to support Tongareva residents after the NZDF personnel have returned home.
While the physical projects are now complete, the NZDF says the relationships formed with the people of Tongareva represent an enduring legacy of cooperation, friendship and shared commitment to a more resilient Pacific.
