BW Digital lands Tonga’s second international subsea cable

Digital infrastructure operator BW Digital announced on Friday that it has successfully landed the Hawaiki Tonga subsea cable in Vava’u, giving Tonga extra international capacity as well as needed resilience.

The 383-km cable, which officially landed on March 18, connects Tonga directly to the transpacific Hawaiki Cable linking Australia, New Zealand, Hawaii and Oregon on the US West Coast, with branching units for American Samoa and New Caledonia.

The Hawaiki Tonga cable – which has been in the works since June 2024 – was jointly funded by Australia, through the Australian Infrastructure Financing Facility for the Pacific, and the Government of New Zealand. BW Digital delivered the cable in partnership with the Government of Tonga and Tonga Cable Limited.

In a LinkedIn poston Friday, BW Digital said work is now underway to prepare the system for commercial service in the coming months.

The Hawaiki Tonga cable is Tonga’s second international subsea connection, and its first direct link to a major transpacific cable system. Up to now, its only source of international subsea capacity has been the Tonga Cable – owned by Digicel Tonga, the Government of Tonga and Tonga Communications Corporation – that connects to Fiji.

The lack of redundancy has made Tonga highly vulnerable to internet disruptions. In January 2022, the eruption of the Hunga Tonga-Hunga Ha’apai volcano damaged both the Tonga Cable and the Tonga Domestic Cable Extension (TDCE), the island nation’s sole domestic subsea cable that connects the main island of Tongatapu with the northernmost island of Vava’u.

The TDCE suffered damage again in 2024 due to an earthquake.
