Rain in Sydney prompted a trip across the Tasman for Let's Be A Star and her trainer John Sargent is one person not so happy to see the winter sun.

The mare has won three races in New Zealand, all on wet tracks, with her most recent over 1400m at Tauranga after two close seconds at Ellerslie.

She has her first test at 1600m in Saturday's Share Care Mile at Warwick Farm on a track still in the slow range.

"The big question is whether it will still be wet enough for her," Sargent said.

"I thought the rain might hang around a bit longer - that's why we brought her over.

"That's against her but she's hard-fit and ready to run a good hard mile.

"She's been working well and it's a home track for her now."

It won't be the mare's home track for long with Sargent due to move his operation to Randwick in the new season.

"It will be good to have boxes on track," he said.

"At the moment we have to hand walk the horses. Randwick will be a lot more work orientated."

Sargent will have 25 boxes at Randwick and will cut his stable at Matamata in New Zealand to 40.

"The prize money in Australia means we can bring the good horses over to compete and that's good for the owners," Sargent said.

One of the horses he hopes will measure up is European import Boogie Shoes who runs in the Tattersalls Mile at Doomben on Saturday, his second Australian start.

The winner of three races in England, Boogie Shoes ran midfield in a 1600m race at the Sunshine Coast on a heavy track.

"He has been bought as a Cups horse, not this year but next," Sargent said.

"The ground didn't suit him at the Sunshine Coast. He is a bit different. He is an English stayer who likes firm ground.

"He will probably just have this run and then go for a spell and we'll get him ready for next year.

"It's the method Chris Waller has used with his imports - a short first campaign - and it's worked for him."

Sargent said Boogie Shoes was a high six-figure investment.

"It's certainly not cheap to buy horses from England anymore but we have high hopes for him."
