"From what I have heard in the wider rural community people aren't particularly satisfied with what has come out of Horizons," Taylor said.
But councillor Helen Craig said a lot of people could be unhappy with Whanganui District Council too.
She didn't see the point of spending "another bucket of money" looking into making such a fundamental shift.
Council chief executive Kym Fell asked what problem the council would be trying to fix.
"We work really well with Horizons. Could we do a better job with the waterways in this area?"
Moving to a unitary authority would be a major change and would take years
Committee chairwoman Kate Joblin wondered whether the same improvements could be achieved by working better with other bodies.
For councillor Rob Vinsen the extra cost made the unitary possibility not worth pursuing.
The matter was referred to the rural community board, to find out whether rural people have a major issue.
