Te Arawa Lakes Trust is confident a 5000 square metre floating wetland planned for Lake Rotorua, will significantly contribute to the lake's future sustainability.
The $900,000 wetland made of fibre mat, is a joint initiative between the Trust, Rotorua District Council and Bay of Plenty Regional Council.
Trust chairman Toby Curtis says it will be a huge asset to help lower the nitrogen and phosporous content of the water, and restore the lake to its previous condition.
He says the trust will be encouraging Maori landowners near the lake to play their part by not putting unwanted nutrients into it.
The district council plans to have the wetland in place before the end of the year.
A smaller scale artifical wetland was floated on Lake Rotoehu in late July.
