Contractors have been resealing State Highway 1 on the south side of the hill.
But they said trucks were damaging the new seal and they were having to redo it.
The Brynderwyns will be closed to all traffic on Sunday, Monday and Tuesday nights from 6.45pm until 5am.
The Transport Agency said there would be detours in place through Waipu and Mangawhai for drivers heading south, and through Paparoa and Oakleigh for northbound traffic.
And it has asked truck drivers to change gear before they arrive at the Brynderwyns heading north.
The agency said speed and gear changes on the new surface were putting stress on the road.
It said it hoped to finish the work by early next week.
