The Government's confident a planned mega-ministry, MCERT, will support RMA and Local Government reforms. 

It expects the Ministry of Cities, Environment, Regions and Transport to be up and running by next July.

It replaces the Ministries of Environment, Transport, Housing and Urban Development. 

Infrastructure Minister Chris Bishop says New Zealand's great challenges involve all those agencies. 

"At the moment, it's all disconnected between three of four different agencies that we're merging together into one."
