The Whanganui and Ruapehu District Councils are considering withdrawing from their regional council and forming a separate, shared regional organisation.
Whanganui Mayor Michael Laws, says the two councils have been discussing the idea for about 18 months.
He says the majority of regional councils in New Zealand don't work.
Mr Laws says communites like Whanganui are facing high rate increases year on year, but gain little from the regional council.
But the Local Government Commission says secession and the formation of a new authority, is a complicated and long-winded process.
