From 7 to 11 March a group of hikers and bushwalkers are taking part in the Trek for Vision, a trek across the South Island of New Zealand to raise vital funds for Vision Australia's Quality Living Groups and Vision Australia Radio.

Sam caught up with one of the participants, Karen Pritchard from Vision Australia's office in Parramatta, who herself has very low vision but is determined to put her hand up for everything and stay fit and active.
