"In order to take part in global research projects, our research and education communities need dedicated capacity that can handle huge data volumes, and provide high levels of reliability. International, collaborative projects are characterised by intermittent, high-throughput, multi-terabit data flows that may last for days.
Building a new cable will further increase the resilience of New Zealand's international telecommunications links and also introduce more competition on the route, as well as providing additional capacity," Adams said.
The Crown had also committed at $15 million grant to Pacific Fibre, the abandoned cable project which was backed by Facebook billionaire Peter Thiel, Trade Me Founder Sam Morgan and Xero's Rod Drury.
Pacific Fibre hoped to rival the Southern Cross Cable Networks' pipe, which is the only link transporting internet traffic in and out of New Zealand. The second cable would bring competition to the market and bring the price of international internet capacity down, Pacific Fibre argued.
Pacific Fibre co-founder Lance Wiggs said today that $15 million just isn't enough money to make a difference to any cable:
"The Government has a lot more resources that they could apply, particularly they could provide a guarantee around capacity...or could have guaranteed loans. It's nice to have but you know, insufficient. Hopefully it is sufficient for Hawaiki, but we've been down this route before," Wiggs said.
Pacific Fibre announced in August last year that the project would not go ahead.
While Pacific Fibre no longer has a pipe in the works, another company - Hawaiki - is planning one.
The Auckland-based company is planning to build a 14-000km cable system between New Zealand, Australia, Hawaii and the US west coast and said earlier this year that the project could be operating within two years.
TPG Telecom, an ASX-listed IT and internet company, has issued a letter of intent saying it plans to acquire fibre capacity on the Australia-United States leg of Hawaiki's proposed cable system.
The main cable would also have branches running to Norfolk Island, New Caledonia, Vanuatu, Fiji, Wallis, Samoa and American Samoa.
Adams said that Southern Cross is expected to meet New Zealand's capacity needs until 2020.
