The stream stretches between Riverslea Rd and St Georges Rd and is already attracting a range of native birds and fish.
On Sunday, June 12 Forest and Bird have arranged for 1700 natives ready to be planted along the waterway.
Volunteers are being asked to message the Forest and Bird Hastings, Havelock North Branch Facebook page to register to participate.
The group will meet at 8.30am with a planting spade at 30 Longlands Rd East.
A private landowner has kindly provided the access point to the stream, and Forest and Bird will have someone at the entrance to point volunteers in the right direction.
