Bill Simpson (treasurer)

Bill has a background in environmental communications and marketing, including education. As a resident of Southshore he is aware of the importance of a healty estuary. His most vivid memory as a child was visiting the Estuary catching flounder. His long term dream is to see the return of the flounder and the water to be safe for swimming. Bill was elected to the Trust in 2011 and has served for 4 years as the Chair till 2016 and is a dedicated member of the Charlesworth Wetland Reserve maintenance team who meet almost weekly to plant, weed and mulch there. Bill believes that Christchurch needs the Trust to be well-resourced and strong so that it can challenge, innitiate and advocate to make sure the estuary is protected and remains as a great recreational, aesthetic and ecological asset for the city.
