A group opposed to the alignment of an expressway on the Kapiti coast says the Transport Agency is being underhanded in its consultation for the project.
The 15km section of the proposed four-lane road from Peka Peka to north of Otaki, forms part of one of the Government's seven roads of national significance. It will cost $250 million to build.
Te Horo Road Action Committee chair Peter Curling says the way the Transport Agency has consulted the public has been poor.
He says in some cases residents are given only 48 hours notice of open days.
But the Transport Agency says the claims have no substance and extensive consultation has been done.
It says there will be plenty more opportunities for the public to have a say on the project.
