Dalton explained in his letter that until details for the next America's Cup had not yet been agreed, the team could not secure sponsorship commitments.
And this is not the first time Team NZ has struggled with money.
Dalton revealed earlier this year that up until winning the Louis Vuitton Cup qualifier on June 12, the team couldn't afford to pay sailors' salaries.
He previously told the Herald that a press release announcing Team NZ's closure was drafted in October 2015, after the board of directors decided that the cash-strapped syndicate had no option but to close up shop.
It was a last minute bail-out from an overseas donor that allowed the team to stay afloat.
Dalton's letter requesting the recent $5 million payout was a response to a series of text messages between Bridges' office and a member of Team NZ about upcoming funding.
The exchange began on June 26 (NZ time), a day before Team NZ won the Cup.
"I've been asked to give you a call to discuss what ETNZ are planning on saying publicly in terms of next steps and any possible support that might be needed should we win the Cup," a text from Bridges' office read.
Exactly a week later, on July 3, the $5 million funding was approved. The Government provided the same amount of funding to Team NZ following its defeat in San Francisco in 2013.
The conditions of the investment that the team agreed to have been withheld.
The Herald on Sunday contacted Team NZ for comment but they did not respond by deadline.
The Government has set a deadline of mid-August for initial advice about Team NZ's plans to defend the Cup in New Zealand in 2021. This will help establish the basis of the next phase - funding and contracting - should the government decide to further invest.
The advice to ministers is set to include potential benefits of New Zealand hosting the 36th America's Cup, timeframes for key decisions, strategic objectives the Government should seek in return for further involvement and recommendations on the next steps.
A group formed by the Ministry of Business, Innovation and Employment, Department of the Prime Minister and Cabinet, Treasury, Sports NZ and other relevant agencies has been tasked with delivering this advice and leading early engagement with Team NZ.
