Marton-based Auret and Parkes have struck up a remarkable relationship and both rarely go a Central Districts meeting without racking up a win.
Parkes ended his apprenticeship with Wanganui trainer Paul Belsham and, every season since, his professionalism has grown, impressing many top judges throughout New Zealand.
Last season, Parkes finished second to northern hoop Matt Cameron in the Jockey's Premiership with 118 wins. This season Parkes sits on 80 wins.
"It really cost me copping a six-week suspension for reckless riding at the start of this season. I still hope I can break 100 for the season with two-and-a-half months of the season to go, but winners are more difficult to come by in winter."
Parkes has ridden two Group One winners during the past 10 years - Ransomed for Gary Vile in the 2013/2014 Spring Classic at Hastings and Miss Mossman for then trainer John Sargent in the New Zealand Oaks at Trentham in the same season.
Ironically, Miss Mossman won four races earlier than Aronmore at Te Rapa on Saturday in the hands of Craig Grylls.
Parkes now has his eyes firmly set on his second 500 starting at the Hawke's Bay meeting tomorrow and again at New Plymouth on Saturday.
"My focus really is on next season when I'll be trying to ride as many winners as I can but, more importantly, more black-type winners," Parkes said.
