The New Zealand sprinter Eddie Dawkins has won the keirin gold medal with Simon van Velthooven taking the bronze on the first day of the international track cycling series in Adelaide.
The BikeNZ contingent are competing in five days of UCI Tier One competition which carries qualifying points for upcoming World Cup events, which in turn qualify riders and teams for the World Championships.
Timaru rider Shane Archbold, currently contracted to the UCI Pro Continental road team An Post Sean Kelly in Europe, returned to the track with success to lead the men's omnium competition after the first of two days.
Archbold, in his first track competition since the London Olympics, was second in the flying lap, third in the points race and he won the elimination.
That leaves Archbold clear at the top after three events on six points ahead of Australians Alex Edmondson on eight and Scott Law 15.
Lauren Ellis and fellow Olympian Jaime Nielsen are in third and fifth positions respectively in the women's omnium.
