"The form out of that race from the horses that finished behind her is good," he said.
"We ran seventh, Volpe Veloce ran eighth and came out and won her next start (Gr.2 Japan NZ International Trophy, 1600m). Boots 'N' All finished ninth and won his next start (Hororata Gold Cup, 1800m) and even the horse of Chris Waller's (Endless Drama) came out and ran fourth in the Group Two (behind Volpe Veloce)."
Kelso had been pleased with the way Supera was performing prior to that run, winning her first two starts this preparation before going on to place in the Gr.2 Cal Isuzu Stakes (1600m) and win the Gr.3 Anniversary Handicap (1600m) at Trentham in January.
"She won the Anniversary very nicely and showed a good turn of foot," Kelso said. "She has got a lot of ability and this is her biggest test."
Supera will jump from the ace barrier on Saturday with Michael Coleman aboard and Kelso said his charge should benefit from the likely track improvement.
"She should get a nice trip from there," he said. "She drew one when she won the Anniversary. The track should come back.
"It was a Slow7 on Tuesday and we have a beautiful day in the Waikato today (yesterday) and the forecast looks okay, so I am hoping it will come back to a Dead4.
Kelso believes Group One winner Volpe Veloce will be hard to beat on Saturday, but he is looking forward to the challenge and will press on towards another black-type assignment with Supera if she pulls through Saturday's run okay.
"I think the topweight, Volpe Veloce, is the horse to beat," he said. "She's proven and is a Group One winner.
"If Supera comes through Saturday well, she will probably go to the Travis (Gr.2, 2000m) two weeks later and then that will probably be her season."
Kelso will also line-up two other runners at Te Aroha on Saturday, including Ginger King, who finished runner-up on debut, and four-win mare Veine D'Or.
"Ginger King ran a nice race at Rotorua first-up and I like the horse, it was a very good debut," Kelso said.
"He has drawn a bit awkwardly at 15, but he should come into 10 hopefully. He is a lovely horse and I expect a nice run from him, I just wish he had drawn a little bit better.
"Veine D'Or, she was very consistent through the summer. I gave her a short break after her last run (at Tauranga in February), while the tracks were really firm.
"She worked well on Tuesday morning, Michael Coleman galloped her and I'm very happy with her work. I think she will be competitive, she has got ability and she should get a nice trip from the draw (barrier 1)."
