Blenheim granddad hitchhikes to Auckland to save the planet

A Blenheim grandfather who refuses to fly to help save the planet spent three days hitchhiking up the islands to meet his first grandchild in Auckland. Seventy-eight year old Bill McEwan has sworn off flying because of its high emissions. Whilst he could have taken a train some of the way, he wanted to make a statement with his trip. The climate activist told Lisa Owen it's something that's become even more important since his granddaughter Rocco arrived.
