The deadline for a decision on whether the Ruataniwha dam gets built has been pushed back three months as its backers grapple with delays in securing funding and signing contracts with irrigators.
And a warning has been issued that more hold-ups could see construction put back by a year.
The scheme's promotor, Hawke's Bay Regional Investment Company (HBRIC), has shifted its crucial "financial close" deadline date from June 30 to September 30 as it talks with potential backers and convinces farmers and growers to sign up to take water.
The company, the Hawke's Bay Regional council's investment arm, has said the $275 million scheme will not proceed if it does not have funding confirmed and deals to sell at least 40 million cubic metres of water a year, just under 40 per cent of capacity, by the financial close date.
Company chairman Andrew Newman told a regional council meeting yesterday the board of inquiry process to determine resource-consent issues related to the project had taken three months longer than expected.
