Ayris began competing in athletics as a six-year-old at the Takapuna Athletic and Harrier Club, but also was a promising gymnast, representing New Zealand in an international event against Australia.[3] She took up the pole vault when she was 13 years old, coached by Jeremy McColl. She finished third in the pole vault at the national secondary schools championships six months later,[3] and won the national junior title at the 2015 national athletic championships.[5] In 2016, aged 15, she became the youngest female New Zealand athlete to clear four metres.[3] In 2018, Ayris won both the national under-20 and senior national pole vault titles,[5] and she subsequently won the national title again in 2020 and 2021.[6]
