If you want to undertake stream clearance at any scale, you will most likely require resource consent.

There are some activities that can be undertaken without consent as a permitted activity.  These are only permitted activities if you meet the conditions for the activity you are doing.  Some of the activities are as follows: 

• Removal of alluvium from structures to protect the structure 
• Maintenance or reinstatement of water intakes other structures 
• Clearing material that has accumulated because of a storm event 
• To manage erosion  
• Controlling aquatic pests 
• Small gravel takes 
• Constructing a sediment trap 

Anything else will require consent. 

Please contact consent.enquiries@orc.govt.nz to make sure you are sure of the rules that apply to you.
