"She is a quiet persuader. Her commitment to a clear vision and her ability to keep people focused is invaluable," her nominator said.
Mrs Ericson, an artist, moved to Waiheke in 1987 and lives near the reserve.
She is a reluctant hero.
"Everybody brings their unique skills to contribute in some way and I'm just one of them really," she said.
She cites locals Tony King-Turner, a landscaper who has worked with the group from day one, and designer Jan Ramp as invaluable to the reserve's development.
The key to the Friends of McKenzie Reserve's successful partnerships is the strong core planning group, publishing clear strategies and constant communication with the council and board, she said.
The local community has also responded positively and there is a goal to use local skills and products.
The focus over the next five years will be finishing tracks, adding interactive learning stations for children and more planting, Mrs Ericson said.
