Aqualink

Overview

The Aqualink submarine cable network is a domestic telecommunications infrastructure connecting multiple coastal locations across New Zealand. Operational since 2001, it serves as a critical backbone for communication and data transfer within the country. The cable links 11 landing points, ensuring robust connectivity between urban centers and regional areas. While its total length remains unspecified, Aqualink plays a vital role in supporting New Zealand's internal communication needs by enhancing data exchange and fostering economic integration across its diverse regions.

As a domestic system, Aqualink is designed to meet the unique geographical and logistical challenges posed by New Zealand's island nation status. By linking key locations along both the North and South Islands, the cable ensures reliable interconnectivity for communities and businesses alike. It supports the nation's growing demand for high-speed internet and data services, contributing to New Zealand's overall digital infrastructure.

Route and Landings

Aqualink connects 11 landing points across New Zealand, spanning both the North and South Islands. On the North Island, the cable lands in Auckland, New Plymouth, Paraparaumu, Raglan, Titahi Bay, Waikanae, Wellington, and Whanganui. These locations represent a mix of major urban centers and smaller coastal towns, ensuring broad coverage for the region. Auckland, as the largest city in New Zealand, serves as a key hub for data exchange, while Wellington, the capital, is another critical node in the network.

On the South Island, the cable lands in Christchurch, Kaikoura, and Oara. Christchurch, as the largest city on the South Island, is an essential point for connectivity, while Kaikoura and Oara provide access to smaller, yet strategically important, coastal communities. The route crosses the Cook Strait, a challenging and dynamic body of water separating the two islands. This connection is crucial for maintaining seamless communication between the North and South Islands, supporting both public and private sector activities.

Ownership and History

Aqualink is owned and operated by One NZ, a telecommunications provider in New Zealand. The cable was ready for service in 2001, marking over two decades of operation. Its deployment was a significant milestone in New Zealand's telecommunications history, as it provided a dedicated domestic submarine cable network to support the country's growing data needs. The system was designed to enhance connectivity between key population centers and regional areas, addressing the challenges of New Zealand's dispersed geography.

The cable's operational history reflects its importance in the nation's digital infrastructure. By connecting multiple landing points across both islands, Aqualink has facilitated economic development, improved access to digital services, and supported the growing demand for bandwidth. While the current operational status of the cable has not been disclosed, its role in New Zealand's telecommunications landscape remains significant.

What Our Measurements Show

Our live monitoring of the Aqualink cable network provides insights into its performance across 18 measured corridors. The best recorded round-trip time (RTT) is 46 milliseconds, while the average RTT is 115 milliseconds. These metrics indicate a reliable and efficient system, capable of supporting high-speed data transfer between its landing points. The variation in RTT likely reflects the geographical distances and technical factors influencing each corridor.

The cable's performance underscores its importance in maintaining New Zealand's internal connectivity. By linking urban centers, smaller towns, and remote coastal areas, Aqualink ensures that communities across the country have access to reliable communication services. This capability is essential for supporting economic activities, enabling remote work, and fostering social connections in an increasingly digital world.
