Statistics obtained by Bain show there have been 18 crashes, which led to 17 deaths, during the 10 years from 2006 to 2015 on SH1 between Toetoe Rd, south of Whangarei entrance, to the SH15A roundabout.
There have been 24 serious crashes leaving 35 people seriously injured and during the same period there have been 51 minor injury crashes, injuring 141 people.
The numbers do not include the fatalities from 2016 or this year.
"Every one of these fatalities is someone's family. In some cases there are children who will never get to know their parents. I'm just horrified by these statistics.
"I know a few people killed on that road and families have never recovered from the fatality and they are still badly affected by it."
With a steady flow of logging trucks, increased tourism and a massive increase in the number of people living in the Bream Bay area, it only meant more vehicles on the road.
"We have an obligation to ensure that roads are going to be safe for Northlanders and visitors that come to our country."
He said the Northland politicians needed to ensure the project, and the next phase to bypass the Brynderwyn hills, were kept to the forefront.
"I want to make sure this project is given some priority. It's a terrible record on this stretch of road that is only going to get busier," Mr Bain said.
"If you drive through Bay of Plenty and the Waikato you see the quality of the roads and I think we have been left behind in Northland.
In August there were a series of public meetings held in Northland by NZTA in which the upgrade options were considered.
The options include upgrading the existing road to a four-lane expressway, upgrading the existing highway for southbound travel and building two lanes to the west for northbound traffic, or building a new four-lane expressway.
A spokesman from the Minister of Transport's office said there had not been any changes to any of the existing transport projects.
Construction on the four-lane upgrade between Whangarei and Port Marsden Highway, a 22km stretch of road, is planned to start in 2019.
