Andrews started cycling competitively aged 14, initially mountain biking but she soon changed to track cycling.[7] She asked her father to pay for dance classes and a deal was made that they would do more cycling. Shortly afterwards, her father bought her a track bike, which got her into track cycling.[10]
At the 2024 Paris Olympics, Andrew became the first woman to win the Olympic gold medal in both the keirin[12] and the sprint[13] at the same games.[14] She had earlier won the silver medal in the team sprint event, alongside Rebecca Petch and Shaane Fulton.[15]
Andrews won Secondary School Sportswoman of the Year at the February 2018 Waikato Regional Sports Awards. A week later, she won the Emerging Talent award at the Halberg Awards.[7]
