The 5-year-old St Josephs Primary School pupil is the fourth generation of her family to take up Highland dancing.
She follows her great-grandmother Doreen Casey, grandmother Mary Pat Hoare, and mother Louise Caulfield, into putting on a kilt and taking the steps.
Courtney was a competitor in the 6 years and under category at the Otago centre's annual piping, Highland and national dancing competitions at the Otago University College of Education at the weekend.
More than 200 people from all around the country competed at the event, which ended yesterday.
Mrs Caulfield, who no longer dances, said Courtney started Highland dancing last September, and instantly showed that the family talents had gone through to a fourth generation.
Twinkle-toed Courtney was not pushed into the performance because of the family connection, but just wanted to dance, her mother said.
She could have more than 10 years of dancing in front of her, as top Highland dancing exams are sat at the age of 18.
Courtney made a success of her weekend performance, winning silver in the 6 years and under grade, performing the fling and the Irish jig.
About 15 girls competed in the grade.
