A major rift has developed between councillors on the Greater Wellington Regional Council, which has been gunning for a super city.
At a meeting on Wednesday, six councillors, including Wairarapa councillor Gary McPhee, backed a proposal to withdraw the council's support for the super-city.
Upper Hutt representative Paul Swain's proposal, prompted by a Nielsen survey which found 26 per cent of people were opposed to the merger, was narrowly defeated in a vote by seven to six.
All over the region, councils are preparing their formal submissions to the Local Government Commission, which is proposing to amalgamate all nine councils and establish eight local boards.
Mr McPhee said the survey was "only a snapshot" but it did show opposition.
