"She has been racing so well and deserves to win a good one," McKay said.
"She went so close in the Sistema. She tried so hard and the 1400m will be much better for her at Awapuni. Reese Jones will ride her again."
Aalaalune was given a brief let-up after the Sistema Stakes and McKay is pleased with her condition going into Saturday's Group 1 assignment.
"She did a bit of quiet half-pace on Saturday and I was really happy with her," he said. "It won't take much to have her spot on for the Sires. She's already race fit."
A win in the Manawatu Sires' Produce Stakes will be a milestone for McKay. He experienced Group 1 success with Puccini when training in partnership with his father, Peter, but a Group 1 win on his account will be a major boost to the 26-year-old's profile.
Aalaalune will be the main focus for McKay this weekend, but he also rates the prospects of his other three Awapuni starters.
Mighty Connor, a 3-year-old gelding by Sebring, quit maiden class at Taupo over 1800m last December and followed up with a couple of placings before finishing eighth in the Group 2 Waikato Guineas (2000m) at Te Rapa last month.
"He beat home Crown Prosecutor and Langkawi that day and the form out of that race is all around him. I'm expecting a bold run," McKay said.
Vittachi won three races for Murray Baker and Andrew Forsman before changing hands and joining McKay's team. While he hasn't won for his new trainer, he has been placed in half of his eight outings from the stable.
"He's a promising stayer and I'd like to have a crack at the Rotorua Cup [Group 3, 2200m] with him, but he needs to win or go close on Saturday," McKay said.
Mr Universe has been placed in his two starts since his maiden win, the most recent a third over 1200m at Ellerslie earlier this month.
"He's a chance on Saturday," McKay said.
