Aitutaki, Cook Islands: Submarine Cable Landing Point

Aitutaki is the second most-populated island in the Cook Islands, an archipelago in the South Pacific Ocean. As an "almost atoll" comprising a main island and fifteen surrounding islets within a lagoon, it sits at a considerable distance from continental landmasses, making submarine cable connectivity particularly significant for the island. One submarine cable lands at Aitutaki, connecting it to a broader Pacific regional network.

The single cable serving Aitutaki is the Manatua cable, which links the Cook Islands with French Polynesia, Niue, and Samoa across a regional South Pacific corridor. This cable represents the entirety of Aitutaki's direct submarine cable infrastructure and places the island within a network spanning multiple Pacific island nations.

Cables Landing at Aitutaki, Cook Islands

The Manatua cable is 3,634 kilometres in length and reached ready-for-service status in 2020. It connects the Cook Islands — including the Aitutaki landing point — with French Polynesia, Niue, and Samoa. The cable is a regional system linking several South Pacific island nations, enabling direct submarine connectivity between these Pacific territories. Aitutaki's inclusion as a landing point on this cable means the island is integrated into a multi-country Pacific network rather than being served by a domestic or point-to-point link alone.

Regional Context

Within the Cook Islands, Aitutaki shares the national submarine cable footprint with Rarotonga, the country's most populated island, which also hosts one cable landing. Together, these two landing points account for all submarine cable infrastructure in the Cook Islands, with the national submarine cable network having been established from 2020 onward. Aitutaki thus represents one of two nodes through which the Cook Islands connects to the broader Pacific submarine cable graph.

Network Role

Aitutaki functions as a single-cable terminus on the Manatua system, rather than a multi-cable hub. Its landing on the Manatua cable places Aitutaki within a regional Pacific corridor linking Cook Islands, French Polynesia, Niue, and Samoa — a network of island nations that share broadly similar geographic and connectivity challenges across the South Pacific. The cable itself, at 3,634 kilometres, reflects the considerable distances that submarine systems must bridge to serve these dispersed island communities.

Within the regional submarine cable graph, Aitutaki's position as one of two Cook Islands landing points on the only cable system serving the country illustrates how small Pacific island nations have structured their submarine connectivity: distributed across a modest number of landing points, each integrated into a shared, multi-nation regional cable rather than served by dedicated bilateral links.
