The Hawke's Bay Regional Council has agreed to delay the report on the review of the Ruataniwha Water Storage Scheme for two weeks to have further advice prepared.
Originally planned for April 26, the report will now be delivered on May 10.
The Council commissioned the review of the key contractual, legal, financial, economic and environmental elements of the scheme, including the impacts and consequences of implementing Plan Change 6 with and without the scheme, as well as the implications of withdrawing from the scheme.
Councillors have received a draft of the review report and during a workshop last week heard from a range of expert advisors who have contributed.
Council chairman Rex Graham says regional councillors have received a large volume of advice, including more than 400 pages of reports, on many critical issues affecting the Council's decision, and have asked for further information.
