"There's a couple of them struggling with injuries right now but there should still been good fields in both races," Millar said. "If I run the 200m time I want I'm confident I can win, although the 100m will be a huge challenge."
Millar is set on running a personal best in the 200m and also has his eye on the New Zealand M19 sprint records.
"I haven't run a fast legal 200 since 2010 so it's a bit overdue. I thought I might have been able to do it at the nationals but there was a big headwind which put me a second outside what I wanted."
Millar's best is 0.1s outside the M19 record and the 200m mark is 20.09, which he's sure he can also topple.
Millar has hardly let up at training at Tauranga Domain since the sprint double, although he had a scare in his final session on Tuesday when he rolled his ankle in a gentle warm-up run. But the injury had settled down by yesterday and he is confident it won't be a hindrance over the weekend.
