Investor Rod Drury told the New Zealand Herald earlier this month there had also been political concerns over the potential of Chinese involvement in the project.
Currently New Zealand's only broadband cable link is provided by the Southern Cross Cable Network, a venture in which Telecom has a 50 per cent shareholding. IDC senior analyst Glen Saunders says Southern Cross extending the estimated lifespan of the cable to 2025 and earlier this year slashing prices by 44 per cent on new customer contracts has perhaps put off "a desperate need" for an additional link.
He says a business case for a future venture might come down to how quickly uptake of the Government-backed fibre network happens.
"If we're using a lot more fibre and bandwidth then ultimately Southern Cross might not be able to cope."
He says the "killer app" that drives a thirst for fibre connections could be five years away.
Telecommunications Users Association chief executive Paul Brislen says his fear is other submarine cable players will be turned off for a long time by the failure of the Pacific Fibre project.
He says the Pacific Fibre business case was predicated on hooking up the Australian market, but with extra capacity being added directly between Australia and North America by other players, the investment rationale gets tougher.
"Without the Australians needing to sign up to a fibre that comes through New Zealand there is very little chance of getting a fibre off the ground that just connects New Zealand to the US because the costs just aren't balanced by the income you would receive from the customer base," Brislen says.
He would like to see the Government back an alternate link, either directly or by committing to purchasing capacity.
"It's a lot of money to be investing in this part of the world, so without a government backing it I think we'd be stuffed."
With the added links out of Australia firing up, the Government needs to move fast as the window for a viable business case closes, Brislen says.
"It would be a crying shame to build this UFB (Ultra-Fast Broadband) and RBI (Rural Broadband Initiative) project and have the world's fastest intranet."
