"When I bought her [Kylie Ree] from Maree Price 10 months ago the deal was that she would get a half share back if the filly got into the Harness Jewels," Brian McCully, the Timaru owner of Kylie Ree, said.
The deal becomes effective after the Harness Jewels at Cambridge on June 5.
"I don't know if I will retain the half share or sell," Price said.
She is a licensed trainer based at West Melton but primarily involved with breaking in horses.
Price and her son, Shane, bought Kylie Ree as a three-month old foal with her dam, Nerokilo, from Peter Robinson.
"She was one of three mares in a paddock on offer and I just liked her on type," Price said.
Nerokilo (by Clever Innocence) won six races as a trotter when trained by Gavin Hampton in the late 1990s.
She has left the winners, Sunero and Daddy Warbucks from six other foals.
Kylie Ree is by Monarchy, the sire of Sovereignty and King Charlie.
Kylie Ree, who started from the second line, finished resolutely to win by a length and three-quarters from pacemaker Paramount Geegee, the winner of his six starts.
Kylie Ree ran the 1950m (mobile) in 2.27.5 (2.01.7), 0.1sec inside the New Zealand record for a filly set by Jo Anne in 2001.
Kylie Ree is the second top stake-earner among the 2yr-old trotters in eligibility for the HJ with $33,955 behind Paramount Geegee with $35,110.
It was her first win in eight starts after three minor placings.
Price trained Kylie Ree until four weeks ago when she passed her to Mark Purdon and Grant Payne to top off for major races.
Purdon drove the filly.
McCully also bought Eric's Legend from Price and her son.
Eric's Legend won four races including a 2008 Sires' Stakes heat at Forbury Park as a 3yr-old from the Purdon-Payne stable and six for Robert Dunn.
McCully transferred Eric's Legend to New South Wales trainer Dean Atkinson in December.
Eric's Legend has had two wins at Harold Park in five starts from his new quarters.
McCully bought the half share off Shane Price in a weanling filly foal by Monarchy from Nerokilo three months ago.
"We will offer her at the yearling sales next year," Price said.
"I have always liked Kylie Ree. She was just like Pocaro when I broke her in. I gave them a 10 out of 10."
Price also broke in Secret Potion and Lancome.
"It normally takes six weeks to break them in but Secret Potion took four weeks longer."
Russley Rascal, a stablemate of Secret Potion and Kylie Ree, confirmed his position as favourite for the 3yr-old colts and geldings section of the Harness Jewels with an easy win against older horses.
The stable has withdrawn Pocaro from the Harness Jewels due to lameness.
Pocaro is the second highest stake-earner among the 4yr-old trotters this season behind stablemate I Can Doosit.
Indulge (Sires' Stakes Consolation) and Spero Denario both entered the top 12 for the Harness Jewels after wins on Saturday.
