Maurice Williamson has attacked his own minister over a transport spat he compared to a "nuclear explosion".
The Pakuranga MP told Transport Minister Simon Bridges his constituents were livid about setbacks to the AMETI (Auckland Manukau Transport Initiative) projects.
He said the New Zealand Transport Agency and Auckland Transport had a "dysfunctional" relationship where "one hand doesn't seem to know what the other is doing."
Mr Williamson blasted the agencies' relationship at a transport select committee hearing at Parliament today.
He said Auckland Transport chief executive David Warburton had displayed an "offensive" attitude to local boards.
