Taupō District Council is demanding changes to the main road on the eastern side of the lake following a truck rolling off the road on Sunday.
It says warnings to Waka Kotahi about the safety of State Highway One have fallen on deaf ears.
The truck was carrying krill oil and milk powder, forcing the road to close for more than twenty four hours as the spillage was cleaned up.
Chief executive Gareth Green says the council has warned the transport agency this could happen for years.
He spoke to Corin Dann.
