Nine-time champion trainer Mark Walker is slightly ahead of the record-setting season achieved by Te Akau Racing in 2020/21.
When Jamie Richards eclipsed the previous record to establish a new benchmark of 160 domestic wins, he had 46 victories by the end of October, while Walker has 54.
After a decade of training for Te Akau in Singapore, where he won champion trainer honours four times, Walker returned to take up the reins again of their Matamata operation on April 1 while Richards was preparing to train in Hong Kong.
He has 20 horses stabled at Riccarton, and will be well represented there on Saturday, including nine in stakes races.
In the Group 1 2000 Guineas (1600m), a race Te Akau have won seven times, Dynastic heads the charge for Walker, along with Cognito and Malborough Bay.
