It would combine one council and one Mayor, speaking with one voice for all of Northland, with a second tier of empowered community boards (which currently exist only in the Far North).
The commission's inability to propose Auckland-style local boards, which have greater powers than community boards and cannot be abolished by the council, may change with an amendment to the Local Government Act which is currently before the House.
"The door is not entirely closed to local boards. It's a matter of watch this space," Mr Morrison said.
The new council will be based in Whangarei with service centres in nine towns, including Kaitaia, Kaeo, Kaikohe, Rawene, Kerikeri and Kawakawa.
Public hearings will be held after submissions close on February 14. If the commission sees sufficient support it will prepare a final plan, with elections in October 2015.
Mr Morrison said the new council would not necessarily reduce rates, but clients would only have to deal with one council.
It was not yet known how many jobs would be lost. The new council would be responsible for redundancies and other obligations of the outgoing councils.
He put the likely costs of the merger at $5-10 million, with similar on-going savings each year, while he believed concerns regarding the Far North being dominated by Whangarei would be mitigated by the proposed ward structure that gave Whangarei and the Far North four votes each. Kaipara will have one.
"At the end of the day, one person one vote is the basis of democracy," he said.
