McCartney played netball and competed in high jump before discovering pole vault at the age of 14.

She came in fourth at the World Under 18 Championships in 2013, then won bronze at the World Under 20 Championships in 2014.

In 2015, she set a world junior pole vault record with a jump of 4.64m. The following year, she won the Emerging Talent award at the Halberg Awards for her sporting achievements.

McCartney’s first major international event was the Rio 2016 Olympic Games, where she took home a bronze medal with a jump of 4.80m.

At Rio she became the fourth New Zealand field athlete to win an Olympic medal and the youngest New Zealand female Olympic medallist.

She has since extended her New Zealand pole vault record to 4.82m at the Auckland Track Challenge in 2017.

Gold Coast 2018 is the first time McCartney will compete at the Commonwealth Games and she will be a medal favourite with her number four 2017 world ranking.

She also studies at the University of Auckland, working towards a career in medicine.
