Atafu, Tokelau

Atafu, Tokelau: Submarine Cable Landing Point

Atafu is a coral atoll in the south Pacific Ocean, forming the northernmost territory under New Zealand sovereignty and one of three islands that constitute Tokelau. Situated approximately 500 kilometres north of Samoa, its 52 islets enclose a central lagoon and together cover a land area of just 2.5 square kilometres. Despite its small size and remote position, Atafu serves as a submarine cable landing point, connected to the broader Pacific digital network through the Tokelau Submarine Cable.

One submarine cable lands at Atafu. The Tokelau Submarine Cable links all three atolls of Tokelau to one another, establishing an intra-territorial connection across the island group. This makes Atafu part of an inter-island corridor that brings fixed submarine connectivity to a community previously dependent on satellite communications alone.

Cables Landing at Atafu, Tokelau

The Tokelau Submarine Cable is a 250-kilometre system with a ready-for-service date of 2023, currently listed at draft status. The cable connects the three atolls of Tokelau — Atafu, Nukunonu, and Fakaofo — forming an internal network entirely within Tokelau's territory. At 250 kilometres, it is a short regional system designed to serve the specific connectivity requirements of these widely spaced but politically unified atolls.

Regional Context

Within Tokelau, submarine cable infrastructure is distributed across three landing points: Atafu, Nukunonu, and Fakaofo. Nukunonu hosts two cables, making it the most connected landing point in the territory, while both Atafu and Fakaofo each host one cable. Atafu's single-cable connection places it alongside Fakaofo in terms of cable count, and both rank behind Nukunonu in the scale of their submarine cable infrastructure.

Network Role

Atafu functions as a single-cable terminus within the Tokelau Submarine Cable system, receiving connectivity through an intra-territorial link rather than an international or intercontinental route. The cable it hosts does not connect Tokelau to external nations; instead, it binds Atafu into a shared network with the other Tokelau atolls, enabling data exchange across a territory whose islands are spread across open ocean. As a draft system with a 2023 ready-for-service date, the Tokelau Submarine Cable represents a recent addition to Tokelau's overall infrastructure, which spans just two cables across three landing points.

In the regional submarine cable graph, Atafu's significance lies in completing the intra-Tokelau ring: without a landing at Atafu, the northernmost atoll of the territory would remain unconnected to the cable network linking its sister islands.
