EonFibre, a New Zealand specialist bandwidth infrastructure provider, is expanding its Trans-Tasman network capability, enabling 400G international connectivity between New Zealand and Australia for customers with high-capacity requirements.

The investment adds international transport capacity that connects with EonFibre’s national fibre network. The new capability is designed for organisations moving increasingly large volumes of data between New Zealand and Australia, including data centre operators, hyperscalers, cloud providers, carriers and enterprises supporting AI and other data-intensive workloads.

EonFibre CEO Richard Mooney says international bandwidth is becoming an increasingly important part of New Zealand’s digital infrastructure.

“AI, cloud and data centre growth mean that customers increasingly need to move very large volumes of data reliably both between their sites in New Zealand and to international markets.

“This investment gives EonFibre significantly more capability across the Tasman and enables us to deliver 400G connectivity, putting us in a strong position to meet future demand as it grows.”

The expansion includes new high-capacity optical capability and additional terrestrial transport capacity connecting international infrastructure into EonFibre’s New Zealand network. The programme has included installation, commissioning and end-to-end testing across the international and domestic transport path.

For customers, the expansion introduces a 400G Trans-Tasman connectivity option alongside EonFibre’s existing international bandwidth services, providing greater flexibility to meet growing capacity requirements. Customers can access high-capacity connectivity between New Zealand sites and data centres and key interconnection locations in Australia through an integrated EonFibre solution.

The capability complements EonFibre’s wider investment in data centre connectivity through DC Direct and Zone Direct, and its FlexWave optical service, which provides dedicated high-capacity wavelength connectivity within New Zealand and to international locations.

“New Zealand is a great option for customers looking to build data centres and take advantage of the opportunities AI is creating.

“But those opportunities depend on having the right infrastructure in place. Our job is to make sure New Zealand has the connectivity to support that growth, both here at home and internationally.”

400G international connectivity

EonFibre’s expanded 400G trans-Tasman capability is now available to customers from November 2026, with services engineered according to customer location, capacity, resilience and routing requirements.
