Bonecrusher raced 44 times for 18 wins, five seconds and 12 thirds, and prize money of NZ$674,225 and A$1,679,495. He was the first New Zealand horse to win over $1 million in prize money. Bonecrusher won three Group One races in New Zealand, including the New Zealand Derby, and six Group One races in Australia, including the AJC Derby, the Tancred Stakes, the Cox Plate, and the Australian Cup.
In the 1986 Cox Plate, Bonecrusher prevailed in the "Race of the Century" with another New Zealand champion, (Our) Waverley Star. Later that year, Bonecrusher was the pre-post favourite against some of the worlds best racehorses in the Japan Cup but contracted a virus in Tokyo, nearly lost his life, and had to withdraw from the race.
