The Tongan community is mourning the death of five coolstore workers when their car collided with a truck on State Highway 2 near Katikati on Tuesday night.
Commander Clifford Paxton says a lot of work has been done to try to make the highway safer.
But road safety campaigner and author of The Dog and Lemon Guide Clive Matthew-Wilson isn't convinced.
"The work that needs to be done is first to slow the trucks down on that section. There needs to be median barriers and there needs to be systems put in place so that when people are pulling out of commonly used driveways like that, there is some warning to them and to oncoming traffic."
He says fatal crashes involving trucks are happening far too often.
In the Government's 2016 Budget, it pledged $85 million for safety improvements on the road between Te Puna and Waihi.
The work was planned to start this year, and expected to include installing median barriers and intersection improvements.
