Vinevale, a six-year-old daughter of Flying Spur, won three races from the Matamata stable of Stephen Autridge and Jamie Richards with the last of those wins being on the Te Rapa track.
She joined the Ruakaka stable after finishing third behind Big Mike at Te Rapa in May and has done all her recent racing on her new home track, winning open 1400m events in her last two outings.
"She's one of those horses that a change of environment seems to have really helped," Gibbs said. "She does 99 per cent of her work on the beach and she loves it.
"Whether or not she's up to the class on Saturday, that's something I'm keen to find out while she's doing so well."
But Gibbs is worried about the track if it gets heavy and may scratch Vinevale this morning.
"She can get away in it up to a slow track, but if it's heavy on Saturday morning we'll pull her out and wait for the open sprint up here in a couple of weeks. I just hope we don't have to do that."
