The couple have already tasted Gr.1 Auckland Cup success as part-owners of Who Shot Thebarman, who triumphed in 2014.
"She's got a rug on her back in a 25-acre paddock in the Whangaehu Valley," said Sharrock, who was also a cup winner in 2012 with Shez Sinsational.
"I'd envisage her having a couple of months off and there are plenty of options for her, but I would love to give her one run right-handed at Ellerslie. That will give her a look around there before the Cup.
"We could have freshened her up and she would have gone very close to winning the Winter Cup without a lot of weight on her back, but she's way better than a winter handicapper.
"She's a serious racehorse. She's won six out of 10 starts and two at Listed level already."
Ladies First's maiden stakes success came in the Listed Rangitikei Gold Cup at Awapuni last month.
