In the “New Zealand Coastal Policy Statement 2010”
- Assess and monitor sedimentation levels and impacts on the coastal environment.
- Require that subdivision, use, or development will not result in a significant increase in sedimentation in the coastal marine area, or other coastal water.
- Control the impacts of vegetation removal on sedimentation including the impacts of harvesting plantation forestry.
- Reduce sediment loadings in runoff and in stormwater systems through controls on land use activities.
