Roadworks on the Brynderwyn Hills are already $3 million over budget, Northland MP Winston Peters says, claiming the blowout will rise and put at risk other vital roading projects in the region.
The New Zealand Transport Agency began the project - said then to cost $15.9 million - in early December 2014 and expected to have the entire project completed by November this year.
In Parliament yesterday, Associate Minister of Transport Craig Foss said the cost had risen from $15.9 million to $18.9 million and he blamed "new information" on geotech issues. Northland MP and New Zealand First Leader Mr Peters said the blowout would likely see desperately needed roading projects, including bridges, in Northland short-changed, or abandoned.
The Brynderwyns improvements continue to cost more each month, he said.
"Northlanders should rightly be able to question why these (geotech) issues weren't allowed for in the initial planning and budget," Mr Peters said.
