Kiwi snow stars test positive for COVID-19 weeks out from start of Winter Olympics

New Zealand's Zoi Sadowski-Synnott, Nico Porteous and his older brother Miguel have reportedly tested positive for COVID-19 five weeks before the start of the Beijing Winter Olympics.

According to 1News, the trio are experiencing mild symptoms.

Sadowski-Synnott and Nico Porteous, both 20, won bronze medals in snowboarding and freestyle skiing respectively at the 2018 Winter Games in Pyeongchang.

Both have shown strong form in the build up to the Games in China and are considered among New Zealand's best medal hopes.

Earlier this month, Porteous claimed his first freeski halfpipe World Cup medal of the season with a second-place finish in Colorado.

Meanwhile, Sadowski-Synnott made a statement by cruising to victory in the women's slopestyle final at the Dew Tour in Colorado.

The athletes were preparing for the World Cup events in Calgary, Canada.

The Beijing Games begin on February 4.
