The ministry would bring together functions across from existing agencies already working in the housing area, and funds to pay for it could come from their existing operational budgets:
• Ministry of Business, Innovation and Employment (MBIE): the housing and urban policy functions, the KiwiBuild Unit and the Community Housing Regulatory Authority
• Ministry of Social Development (MSD): policy for emergency, transitional and public housing
• Treasury: monitoring of Housing New Zealand (HNZ) and Tāmaki Redevelopment Company
Twyford said the super ministry would end the fragmented approach caused by involving a number of agencies.
MSD would continue to manage the housing waiting list.
Twyford told Radio New Zealand the move was aimed at providing more houses in a more efficient, capable and accountable way.
He said there was very little capability to deliver Kiwibuild. "We're having to build that pretty much from scratch."
An urban development authority would be established to be the "delivery agency" for Kiwibuild and large-scale development projects.
"That would be a powerful delivery agency to speed up the building of housing and these large complex development projects.
"We need an end-to-end approach to the whole housing system."
