Rarotonga, Cook Islands: Submarine Cable Landing Point

Rarotonga is the largest and most populous island of the Cook Islands, a Pacific island nation, and serves as one of two submarine cable landing points in the country. The island is home to the national capital, Avarua, and hosts approximately 72% of the Cook Islands' population. One submarine cable lands at Rarotonga, connecting it to a broader network of Pacific island territories and providing the island's first direct submarine cable link, which became ready for service in 2020.

The cable landing at Rarotonga forms part of a regional South Pacific corridor, linking the Cook Islands with French Polynesia, Niue, and Samoa. This positions Rarotonga within an inter-island and regional connectivity framework spanning several thousand kilometres of open ocean, characteristic of submarine cable infrastructure serving dispersed Pacific island communities.

Cables Landing at Rarotonga, Cook Islands

Manatua is the sole submarine cable landing at Rarotonga. The cable has a length of 3,634 km and reached ready-for-service status in 2020. In addition to Rarotonga, the Manatua cable connects the Cook Islands with French Polynesia, Niue, and Samoa, forming a multi-country loop across the central South Pacific. Rarotonga represents one of the Cook Islands' two landing points on this system.

Regional Context

Within the Cook Islands, Rarotonga shares the country's submarine cable infrastructure with one other landing point: Aitutaki, which is also served by a single cable. Together, these two landing points constitute the entirety of the Cook Islands' submarine cable network. Rarotonga, as the most populous island and seat of government, represents the primary node in this two-point national system.

Network Role

Rarotonga functions as a single-cable terminus within the Manatua system, which links four Pacific island territories across a span of 3,634 km. The cable's reach to French Polynesia, Niue, and Samoa means that Rarotonga is integrated into a regional Pacific network rather than serving as an isolated endpoint. The 2020 RFS date marks the beginning of submarine cable connectivity for the Cook Islands as a whole, with Rarotonga as its principal landing node.

In the broader regional submarine cable graph, Rarotonga's position on the Manatua cable places the Cook Islands within a multi-territory South Pacific ring, connecting communities that were previously dependent on satellite communications for international data links. This makes Rarotonga a meaningful point in the evolving submarine cable map of the central Pacific.
