Slimline is expected to be in the thick of the action at Tauherenikau today.
The 6-year-old has a smart black-type record and she looks well placed to pick up another credit in the Listed WRC and Pope & Gray Contractors Wairarapa Thoroughbred Breeders' Stakes WFA (1600m).
"I'd think Asama Blue would be pretty hard to beat, but my mare is very well and it's the right sort of race for her," trainer Gary Vile said.
Slimline won the Listed Anzac 1550 last season and she also finished runner-up in the Listed Rangitikei Gold Cup (1550m).
This term, the mare was successful in an open handicap before she ran third in the Group 2 Manawatu Challenge Stakes (1400m).
