The Rangitaiki River Scheme Review panel has been granted more time to process and interpret a large quantity of information before finalising the review report.
The independent Review team, led by Sir Michael Cullen, is looking into the infrastructure and the circumstances that led to the breach of a flood wall and associated flooding through the town of Edgecumbe in April.
Bay of Plenty Regional Council commissioned the review in the days after the event, requesting the report be completed in July.
"When I announced this review, I said that it was imperative that the review was undertaken with all possible speed as we wanted to make sure that any improvements identified could be acted on promptly. And this hasn't changed for us," said Regional Council chairman, Doug Leeder.
"However, in light of the volume of technical information that the review panel is processing within the scope of the terms of reference, the review panel has asked for additional time to ensure a considered and thorough response which means that it may be a few more weeks before this review is completed.
