The Tony and Lyn Prendergast-trained mare, who has a rating of 75, was nominated in the rating 85 1400m and a combination of factors means she will now carry 52kg after the Prendergasts engaged apprentice jockey Toni Direen, who has a 2kg claim.
''There was no rating 75 race for her, so that's why we put her in the rating 85,'' Tony Prendergast said.
''She's on the minimum weight [of 54kg] and we take the claim off it.''
The 5yr-old daughter of O'Reilly finished well to win at Omakau on January 3 carrying 54kg, before a second at Gore and a fifth at Wingatui on February 2. She finished fourth behind Ridley at Riccarton last Friday.
''She just got a bit further back than she normally does [at Riccarton], and she had to put in a big run,'' Prendergast said.
''She just came to the end of it a little bit just short of the line, but we expect her to go pretty well.''
When asked what work she had done since Riccarton, Prendergast's answer was simple.
''Nothing,'' he said.
''She doesn't take a lot. She's pretty natural and a good-winded mare, so you don't have to do a lot with her.''
Semper Plus has been mixing her form, but was impressive winning for John and Karen Parsons at Wingatui on February 2, while Redfern is dropping back to 1400m after failing over the mile at Ascot Park.
The Prendergasts have been patient with Kays Unite (race 4), who won a trial at Rangiora at September before being put aside.
''She went shin-sore, so that's the reason for that gap,'' he said.
''She's got quite a bit of speed, but she's still a bit green, so a 1100m maiden should suit her down to the ground.
''She's not all that big but we'll keep our fingers crossed.''
Prendergast feels Asaint Sheaint (race 7) is rather unfairly named, even if she was a bit short of ring craft when she made her debut at Ashburton in December.
''I don't know why they called her that, really, because she's a really nice mare,'' he said.
''She just did a few things wrong - she over-raced and was a bit field-shy and was bumped around it. It's best forgotten, that run at Ashburton.
''She's quite a nice maiden, but she's got a bit to learn.''
