There was a small reward at the last World Cup event in Los Angeles, when Mitchell was second in qualifying. Signs were there.
Mitchell qualified fourth fastest in Kong Kong in a personal best time of 9.767 seconds - fellow Aucklander Webster was ninth and Southlander Dawkins 19th - and beat former multi-world champion Francois Pervis of France, before losing his semifinal to eventual champion Russian Denis Dmitriev.
"As for making history, our whole sprint squad is going really well and it could have been any one of us," said Mitchell. "I'm pretty new to the whole [individual] sprinting thing.
"I am fortunate to have mentors like Sam and Eddie, Anthony and the coaching staff to pave the way, really."
With the classy endurance rider Aaron Gate taking silver in the slimmed-down omnium - cycling's equivalent to the decathlon - New Zealand had five medals going into last night's final night of the event, a year after a Rio Olympics failure that cost Cycling New Zealand $500,000 in funding.
Gate won gold in the same event in 2013, before it was rejigged and slimmed down.
Timed racing events, such as the time trial, flying lap and individual pursuit, have gone, but a tempo bunch race is in and it's now raced over one day.
Gate was pipped by France's Ben Thomas in the final sprint of the 40km points race, which proved the difference between gold and silver.
The five medals match the efforts of Melbourne in 2012, Cali in 2014 and Paris a year later.
