He is best known for his three consecutive wins in the Railway Stakes (1,200 metres) at Ellerslie, the country's premier sprint race for thoroughbreds.
Trained at Matamata by Dave and Paul O'Sullivan, the gelding was bred in Australia by International Thoroughbred Breeders, Inc.
[1] Dave O'Sullivan, one of the most successful trainers in New Zealand racing history, labelled Mr Tiz "the greatest racehorse I've ever trained".
[1] Mr Tiz showed his potential from very early in his career, being placed in his first two starts before a maiden win at Paeroa at his third raceday appearance.
Yet from that impossible position, under a huge weight - and in a sprint race - Mr Tiz, ridden by regular jockey Lance O'Sullivan, stormed along the rail to win.
[2] Later in the month, he finished second in the Telegraph, carrying a crushing 60.5 kg - and handicap weight given due to his brilliance.
Near the back of the field at the home turn, and seemingly in a hopeless position with 300 metres to run, Mr Tiz showed a breathtaking turn of foot and made up an extraordinary amount of ground to record one of the greatest wins by a New Zealand horse on Australian soil.
