"Yet, just up the road from the Centennial highway, the Government has cancelled plans for further barriers.
"These are very dangerous roads, and the cost of the barrier is peanuts compared to the cost of building a new highway."
NZTA spokesman Andy Knackstedt said the two wire-rope median barrier projects on the Kapiti Coast had not been deferred, not cancelled.
Both remained in the NZTA's forward work programme for 2012-15, he said.
Chris Lane, director of the Kapiti emergency medical services, backed Mr Matthew-Wilson's call.
Dr Lane, who has attended serious and fatal crashes on SH1 in the district in the last 20 years, believed that the high number of serious crashes would continue on the highway, until median barriers were installed.
"The Government should make these wire rope barriers its top priority, far ahead of building new roads that may not be ready for years," Dr Lane said.
