"Reviewing the council's overall ability to deliver could provide critical insights needed to identify new opportunities and direction as well as better achievement of existing priorities.
"A successful organisational review could lead to improvements in processes, structure and skill development.
"This in turn could result in increased productivity and efficiency, and increased staff satisfaction and engagement stemming from staff having a better idea of what is expected of them."
A report would come back to council on August 8 for the selection of a preferred provider and a final scope, timeframe and costs would only be known from the proposals received.

Ōtaki ward councillor James Cootes, who sought a review, said terms of reference will be determined to guide the organisation which does the review.
"It is imperative that we select a company capable of doing the review impartially and with integrity.
"As I've said previously we have some fantastic staff within the organisation doing lots of really great things. We also have teams incredibly stretched.
"The review, I have no doubt will reflect that, but will also find the areas that need improvement, to lift our performance, our culture, our reputation."
