By funding a wide range of high priority projects the Foundation seeks to maintain and improve the educational, cultural, spiritual and recreational environment of the School. The ultimate aim for the Foundation is to secure the long-term future of the School, ensuring Whanganui Collegiate School continues to flourish and inspire future generations.
