The Ruataniwha Water Storage Scheme's financial viability will be re-examined by independent auditors after concerns were raised by some Hawke's Bay Regional councillors last week.
Following an extraordinary Hawke's Bay Regional council meeting on Friday, council authorised a drawdown of $80million, less development costs, for investment in the scheme.
Council had agreed that three of four conditions required before investment could proceed had been met, and an independent financial review from auditors Deloittes supported the content and conclusions of the business case as being robust.
However yesterday, Hawke's Bay Regional Council chairman Fenton Wilson confirmed Deloittes will be re-checking the figures provided by the Hawke's Bay Regional Investment Company Ltd (HBRIC).
He said Deloittes were maintaining the break even point for the project was to be water uptake volume of 41.5 million cubic metres.
