There were some big casualties along the way, with Golden Shears speed shear winner Paerata Abraham eliminated in the heats, and event organiser and New Zealand Rural Games Speed Shear winner Jack Fagan, of Te Kuiti, making the semifinal cut of 12 but then just missing a place in the top six for the final shootout.
Jones had been among the top competitors in other speed shear events in the North and South Islands this year, and won the Aotea Sports Club speed shear in Dannevirke on February 2.
Golden Shears senior shearing champion Forde Alexander, of Taumarunui, underlined his prowess in the short-form of the speed shear arena by winning Saturday night’s senior final.
The victory blocked the possibility of a UK double, with Callum Bosley from Cornwall, England, having to settle for second place.
Sean Fagan, of Te Kuiti, was third and Cheyden Winiana, of Nuhaka fourth.
Jack Fagan and King Country teammate Clay Harris, of Piopio, beat Jones and Welsh teammate Gethin Lewis in a speed shear relay of one sheep each.
The speed shear was the fourth in the five rounds of the JR King Country Speed Shear Circuit, in honour of shearer and father-of-two James Ritchie who died in a crash west of Te Kuiti in February 2018.
Earlier rounds this season were at Matiere, Taumarunui and Aria.
The final round will be on April 4 - the first day of the season-ending New Zealand Shears in Te Kuiti.
Earlier on Saturday, Jones and Lewis were to have shorn in the second Wools of New Zealand Shearing Series test, of 20 sheep each, against the New Zealand team of Abraham and brother-in-law David Gordon, at the Waitomo Caves Sports shearing championships.
However, the sports, including the shearing, were cancelled due to heavy rain.
