Caduceus was a New Zealand bred Standardbred racehorse. Caduceus is notable for winning the 1960 Inter Dominion Trotting Championship, trotting's premiership event in Australia and New Zealand, from a handicap of 36 yards, in front of a world record crowd.  Prior to this in New Zealand, he had won major events including the New Zealand Free For All sprint race on three occasions plus the Auckland Trotting Cup.
In 1960, he went to the United States, the first to prove he could match the very top US horses. He ended up winning more than £100,000, with gallopers Tulloch and Sailor's Guide as the only horses bred in Australia or New Zealand to have achieved this distinction at that time. .
1960 Inter Dominion
Without doubt the most memorable is that which took place on 13 February 1960 at Harold Park, Sydney, when the "mighty atom" Caduceus from New Zealand defeated Australia's Apmat in the final of the Inter Dominion before a world record crowd of 50,346. Caduceus and Apmat had been singled out as the best two chances in a star-studded final field, and throughout the heat series, it could be seen that the rivalry which existed between these two great horses had been carried on to their drivers Jack Litten of New Zealand on Caduceus, and the local champion, Bert Alley on Apmat.
People crammed every vantage point to watch the race. They were jammed on every square inch of the inside greyhound circuit and packed into what is now the centre-course carpark. Those who were unable to see in the grandstand tore down timber and three ply partitions in the main grandstand. In a spectacular finish, Caduceus passed the post half a length clear of Apmat, with the Victorian Maestro's Melody a neck away third and Fettle a close fourth. Caduceus received one of the most deafening ovations ever heard on a racetrack, but whilst the cheers were still sounding, the news was announced that a protest was lodged by Bert Alley against Caduceus being declared the winner. This produced a most unfavourable reaction from the crowd, strange in the circumstances for they had turned against their own local horse. The Stewards, however, dismissed the protest and Caduceus was the winner of one of the most exciting sporting events ever held in Sydney.
In 1960, aged nine, Caduceus went to the United States to compete in the annual Yonkers Raceway International Series. Caduceus showed he was the equal of the top American horses, even winning the last race of the series, only to be disqualified. He was then leased to American interests, and at 10 years was still winning races. He won 82 races before he was returned to New Zealand and sired 18 winners before his early death after only two seasons at stud.
