Pacific Fibre hoped to rival the Southern Cross Cable Network's pipe, which is the only link transporting internet traffic in and out of New Zealand.
The second cable would have brought competition to the market and the price of international internet capacity down, Pacific Fibre argued.
This, it said, would allow internet companies to increase the monthly data caps they offer, so users could take advantage of the faster speeds of the Government's $1.5 billion ultra-fast broadband network.
The UFB scheme aims to provide download speeds of 100 megabits per second to 75 per cent of New Zealand by the end of 2019.
Drury, Pacific Fibre's co-founder, said the cost of New Zealand broadband made it hard to connect globally and it was "this market failure" the company had been looking to address.
"We still cannot see how the Government's investment in UFB makes sense until the price of international bandwidth is greatly reduced," Drury said.
But Economic Development Minister Steven Joyce said yesterday there was no issue with capacity on the Southern Cross cable and that retail prices for broadband were "dropping quite significantly".
A senior market source suggested the failure of the business was less of a capital markets problem and more about issues with Pacific Fibre's business plan.
"The issue was whether or not the business plan was going to work in a highly competitive market where you have got incumbents."
One potential investor could have been the $19 billion New Zealand Superannuation Fund.
But a spokesperson for the fund said it undertook extensive due diligence on Pacific Fibre but was unable to "gain enough confidence" in the opportunity.
"Any investment we make needs to generate sufficient returns for the risk we have to take on, relative to other investment opportunities both domestically and internationally."
The company will now be wound up and its six staff have been given notice.
Telecommunications Users Association chief executive Paul Brislen said the news was "devastating" and it would mean there would be a lack of competition in the international capacity market.
"We're stuck with one provider and that's never a good sign for any industry."
Although Chinese-backed company Axin flagged its intentions last year to build a 3000km cable between Australia and New Zealand, Brislen said there had been little noise from it recently.
Morgan said there was "plenty of talk but very little walk" from other players who spoke about a cable project but the Pacific Fibre team were the only ones who "put their money where their mouth is".
