A group representing three thousand commercial and residential builders says urgent action is needed from whichever party leads the next government to shore-up a vital sector.
Master Builders has today released new research on the state of the industry and a challenge to political parties.
It says the building industry has for too long been caught up in a boom and bust cycle that government can change.
It wants housing to be designated as "critical infrastructure" ; prioritisation of public building and infrastructure projects during down-cycles and a speeding up of consenting.
Master Builders Chief Executive David Kelly says if changes aren't made more builders will fail and the homes, schools and hospitals needed around the country won't get built.
