Carterton mayor Ron Mark said Wairarapa mayors would "keep talking" with the Local Government Reform Working Party but is adamant their offer of participation has no substance.
Porirua City councillor Ken Douglas, who chairs the working party, said he was disappointed by reports that Mr Mark, South Wairarapa mayor Adrienne Staples, and Masterton mayor Garry Daniell believed they were not invited to participate in discussions concerning local government reform.
He said that was not the intention of his letter, sent on December 21, which calls for a meeting to share information and discuss issues in common.
Mr Mark described the invitation as "patronising" and called it a "Clayton's offer".
"We will not be sitting at the working party table with equal status," he said.
