He was believed to be catching the train to work in Wellington city, but police said it was unclear whether he did so and were making inquiries.
He was last seen wearing a dark hoodie, a green or blue shirt, navy blue trousers, and black work boots.
Police described Saunders as being 178cm (5'10) tall, of slim build, with short dishevelled hair and a short beard.
They asked anyone who had seen Saunders or knew were he was to call 111.
