The three Wairarapa councils will merge into one if an application made by Masterton District Council is passed.
At a Masterton District Council meeting yesterday, councillors voted seven to four for a Wairarapa unitary authority.
An application will be made to the Local Government Commission for the reorganisation of South Wairarapa, Carterton and Masterton district councils which will mean a single Wairarapa council would be responsible for all district and regional activities.
Councillor Gary Caffell put forward an alternative council amalgamation which suggested the amalgamation of the three Wairarapa councils and the retention of the Greater Wellington Regional Council in its current form.
Mr Caffell said in an email exchange with Carterton Mayor Ron Mark, who has actively supported the unitary authority, that Mr Mark said 51 per cent of Carterton people wanted no change but were smart enough to know legislation had changed and they must make a choice.
