Critics aren't convinced the Government's new mega-Ministry will work.
It's merging the environment, housing and urban development, and transport ministries into a new Ministry of Cities, Environment, Regions and Transport.
Right-wing think tank NZ Initiative executive director Oliver Hartwich says it will still report to the same number of ministers.
He told Heather du Plessis-Allan having it fully operational in six months is also ambitious.
Hartwich says the ministries are busy with RMA reforms, which are taking up all their resources.
He says putting a super merger on top of that could be asking too much.
