Milly Clegg

Auckland United

Clegg played her first minutes of senior football with National League side Auckland United, helping them to win the Kate Sheppard Cup in 2022 before making her National League debut with them.

Wellington Phoenix

She then joined the Wellington Phoenix, the only New Zealand team in the Australian top-flight women's league, for the 2022–23 season. She was not paid while playing with the Phoenix, in order to retain amateur status and so maintain NCAA eligibility, considering playing college soccer in the United States in the future. Becoming the Phoenix's top scorer with four goals, she was offered different options to continue with them, including a multi-year professional contract, but rejected the Phoenix to join their rivals, Australian side Western Sydney Wanderers FC. She has also declined to be paid by this club.

Racing Louisville

In January 2024, NWSL club Racing Louisville announced the signing of Clegg on a three-year contract. In January 2025, Clegg was loaned to Canadian club Halifax Tides for the inaugural season of Canada's top tier Northern Super League. She scored her first goal for the Tides in a 1–1 draw against Vancouver Rise FC on 27 September 2025.

As a youth international, Clegg represented New Zealand at the Under-17 and Under-20 World Cups. At the 2022 Under-20 Women's World Cup, she scored in the third minute of their 2–2 draw with Colombia, the last match as they exited in the group stage. At the 2022 Under-17 Women's World Cup later that year, she scored New Zealand's only goals in two 1–3 defeats. With New Zealand looking for more goalscoring threats ahead of their home Women's World Cup, Clegg was called up and made her debut for the senior team on 7 April 2023 in a friendly against Iceland. On 30 June 2023, Clegg was called up to the New Zealand squad for the 2023 FIFA Women's World Cup, the youngest player in the team. The tournament is her third World Cup in under 12 months, a feat matched by Colombia's Linda Caicedo, leading Clegg to be described as "an absolute unicorn" by New Zealand sports podcast The Niche Cache. On 4 July 2024, Clegg was called up to the New Zealand squad for the 2024 Summer Olympics.
