The group is more than halfway there and is asking for help in the form of donations.
Bill Reymer (pictured) and his family own 820m of stream bank.
Bill has retired the majority of the steep riparian margins on his farm and there is a good mixture of mature mānuka, tōtara, native ferns and rimu.
Funds raised will help plant a wetland area alongside the stream and understory planting beneath the mature trees to help prevent weed establishment and filter sediment on the steep slope.
The native plants used will include carex grasses, harakeke (flax), cabbage trees, ribbonwood, and kahikatea in the wetter areas along the water.
Further up the bank will be toetoe, mānuka, coprosma, tōtara, kānuka, kawakawa and kōwhai.
The group is raising money to prepare the site, plant at the site and carry out two post-care visits to maintain the planting.
The budget also includes the cost of 5500 native plants and trees.
Funds raised will be used on materials to control erosion as well as Million Metre's 15 per cent administration fee.
