At-risk sites have been identified through document and report review, consultation and a drive-over exercise. In total, twenty three sites have been recognised as potentially problematic, comprising rock fall, landslide, flooding, coastal erosion and debris flow hazards. The sites are shown on the project map.

Each of the sites has been assessed in terms of its geological, environmental and economic issues and their contributions to route security with an attempt to prioritise sites in terms of seriousness and urgency. The following ten sites are considered the most problematic:
- Newman’s Slip (landslide)
- Meybille Bay (rock fall)
- Stilts Bluff (landslide)
- Rapahoe (coastal erosion and rock fall)
- Hawks Crag (rock fall)
- Omoeroa (Fox Hills) (debris flows)
- Uranium Point (rock fall)
- Bruce Bay (coastal erosion)
- Woodpecker Bay (coastal erosion)
- Diana Falls to the Hinge (rock fall/landslide)
However, the issues experienced at these sites are typical for their general area. Consequently, this Study has developed a ‘Corridor Management Strategy’ over an individual site approach, which is considered a more cost effective solution to reducing natural hazard risk along the route.
