O'Cartier, the well-performed sprinter, is back in work as a 9yr-old with John and Karen Parsons at Balcairn.
"We had thought about retiring him but he just loves to be in work," Bev Jones, the Mossburn owner-breeder of O'Cartier, said.
O'Cartier has amassed 16 wins and $442,147 in stakes. The My Halo-Carinda gelding had to be content with four minor placings in 11 starts last season. He had his last win in the listed Lightning Handicap at Trentham in April, 2011.
O'Cartier won the Lightning Handicap in 2008 and finished second and third in the race the next two years.
He won the group three Challenge Stakes at Awapuni in 2009, dead-heated for first with Coup Bloomsbury in the 2007 Stewards' Handicap at Riccarton and won an open sprint at Te Rapa in 2009.
O'Faberge, a brother to O'Cartier, resumed racing at Riccarton last Friday. He has won twice from six starts for the Joneses and Parsons stable.
Another half-brother, Santos, has won three races and finished second to The Solitare in the Dunedin Cup. His dam, Carinda, is due to foal to Pins.
• Dunaden and Americain head the weights for the $A6.2 million ($NZ7.8 million) Melbourne Cup with 58kg, AAP reports.
Dunaden, the winner last year and Americain (the 2010 winner) will have to prove the equal of Makybe Diva to win again.
