On Tuesday the work crews carried out a "tidying up" programme which also included removing some vegetation spots.
Detours were put in place at both ends of Breakwater Rd between the two main Napier Port entrances also under traffic management control some port traffic was able to use the stretch.
As well as closed to general traffic the road and footpaths were also closed to cyclists and pedestrians while the work was carried out.
The bluff face inspections would continue to be carried out for safety reasons, probably every two years, the spokesperson said.
