"He is as ready as we are going to get him. Troy (Harris, jockey) will give him a little quiet trot and canter (Thursday) to make sure everything is 100 percent.
"It is mainly just to check that he is happy down here and that Troy is happy with him. After his gallop at Te Aroha last week I think we are pretty much right."
A former top-class jumps jockey, Chipperfield is pinching himself as to how smoothly the campaign has gone for the electric son of Darci Brahma who has won his past four races with ease.
"We have been very lucky," he said.
"We made some plans after he won his first trial back in March. Every race we have targeted for him he has just got better and better and he keeps winning them. It has been a faultless preparation."
Raced by The Oaks Stud, strong supporters of the emerging trainer, Chipperfield said the temperament of offspring by the stud's resident sire went a long way to making them good racehorses.
"Full credit to the Darci Brahma breed. All Darci geldings are like him, they are relaxed and take everything in their stride.
"Catalyst worries about absolutely nothing. His last three races he has had to travel the night before and he eats up and just enjoys it. Nothing bothers him and that is a huge asset to him." – NZ Racing Desk
