Sykes has spent time sparring with Commonwealth Games gold medallist David Nyika (Hamilton) this summer.
Ellis, who trains heavyweight Nyika, said Sykes was looking sharp.
"He has looked really good. His agility is good, his stamina is good and he is taking really good options."
Sykes and Auckram have fought each other before, at the nationals in Invercargill last October. Ellis said Sykes lost that match-up in a close fight. The pair are the country's highest-rated light heavyweight amateurs but only one can be sent to China.
Sykes has about 90 fights next to his name and is coached by father Mike Sykes at their family gym, Sykes Boxing Gym on Tania Cres.
