"So we are making public the figures we supplied some months ago to put an end to the perception that we have been somehow holding back."
The numbers show the regional council's main spend in Wairarapa is flood protection, which costs $3.3 million in the region, and draws $2.14 million in rates. The next biggest cost is public transport, which accounts for $3.22 million, but is allocated only $700,000 in rates from Wairarapa.
Mr Simpson said the figures had been reviewed by PriceWaterhouseCoopers.
"We have always acknowledged that allocating spending between geographical areas involves an element of estimation," Mr Simpson said. "But PriceWaterhouseCoopers has confirmed that our figures provide a good general picture of regional council spending in Wairarapa."
Working party chair Lyn Patterson said council supplied the figures to the working party in as much detail as it was able to and these were included in the Morrison Low report.
She said they accepted these as advised by Greater Wellington but as they were based on estimates, they were unable to determine the exact amount spent.Figures supplied to the Times-Age by Greater Wellington Regional Council (GWRC)
