"We didn't really want to run him first-up at a mile," co-trainer Andrew Forsman said. "We thought it would be better to get this run into him and then up to a mile second time when I think he's going to be much more competitive.
"He's probably a run behind a fair few of them as there's not many that are fresh-up into it. So he's going to need the run a bit.
"He's drawn 10 of 12 so he's going to get an awkward sort of a run, so nothing really points toward him being competitive, although we wouldn't be surprised to see him run a cheeky race."
Authentic Paddy is in top order for today's Tarzino Trophy at Hastings, according to trainer Lisa Latta.
"He went a good race in the Foxbridge Plate and he's very well in himself," the Awapuni horsewoman said. Fifth when resuming last time out in the Group Two feature at Te Rapa, Authentic Paddy is a multiple Group One placegetter and he will be ridden for the first time by Leith Innes.
