Steve Anderton will rely on The Diamond One to defend the stable's title in a coming southern feature.
The Wingatui trainer won the listed Valachi Downs South Island Thoroughbred Breeders' Stakes with The Solitaire last year and The Diamond One will attempt to follow her lead at Riccarton on March 22.
''It's a nice race for her and she's put the weight back on since she came home,'' Anderton said.
The Diamond One won the Gr.3 White Robe Lodge Handicap in early February to earn a crack at the Gr1 Haunui Farm WFA Classic at Otaki, where she finished a respectable sixth behind Nashville.
''She lightened up a bit on the trip and her run wasn't too bad,'' Anderton said.
''I feel she's still six months away from being ready to have a go at those sort of races, but it did give us a line on where she's at.''
The Glitzy One will also be in action on Valachi Downs day with the Seaton Family Hororata Gold Cup her likely aim as a lead in to the Carriers Arms Hotel Riverton Cup on April 19. She finished third in the listed event last year.
Meanwhile, The Solitaire has taken no harm from her unplaced run in Saturday's Gr1 New Zealand Stakes at Ellerslie.
''She got a bit stirred up before the race, but she's not a sit and sprint horse,'' Anderton said. ''She loves the pace on and can then finish over the top of them.
''She comes home on Thursday and I'll get her ready for the Canterbury Gold Cup.''
All three mares are raced by their breeders the Dennis brothers and Anderton is optimistic he has another potential star for the family.
''I've got a two-year-old full-brother to The Jewel that I've just sent back to them for a break,'' he said. ''He's won a jump-out and I really like him.''
