Councils in the Wellington region are considering options for the future governance of the region, and Wairarapa councils have agreed on a preferred option of a unitary authority.
Leaders disputed the amount subsidised by Greater Wellington this week when they argued Wairarapa can afford to become a unitary authority.
Figures provided to then-Carterton Mayor Gary McPhee in 2008 estimated the subsidy to be about $4.5 million, but figures provided in a report commissioned by the three Wairarapa district councils estimated this figure to be $11.2 million, and the mayors questioned why the figure was so high.
Ms Wilde said the report has a host of inaccuracies and the spend could not easily be reduced.
"The report paints a picture of regional council services that are either over-priced, unnecessary, unnecessarily comprehensive or easily abolished," she said.
