Campbell Stewart has won New Zealand's 19th medal at Tokyo Olympics

Cyclist Campbell Stewart has won New Zealand's 19th medal of the Tokyo Olympics after claiming silver in the men's omnium today.

Great Britain's Matthew Walls takes gold in the omnium with 153 overall points, while Italy's Elia Vivani won bronze with 124 points.

Campbell came second with 129 points.

Stewart replaced Aaron Gate in the omnium after Gate was ruled out of the rest of the Olympics after coming off his bike at 66km/h - shredding the skin off his right shoulder and breaking his collarbone - last night during the men's pursuit bronze race.

The 23-year-old was world champion in the omnium in 2019. This is his first time competing at the Olympics.

Congratulations Campbell!
