Now she is in the New Zealand Development Squad and loves synchronised swimming.
She is also in the New Zealand Swimming Squad, making her a very busy teenager.
Pratt says her daughter is "very passionate and very talented at both" sports and doesn't want to choose one sport over the other.
Zyleika was one of 21 swimmers representing Tauranga Synchro, ranging in age from 9 to 20, at the national synchronised swimming competition. The Tauranga club came home with an impressive medal haul proving that once again, Tauranga is a major player in the sport.
The local swimmers were just a small part of the 170 athletes from 10 clubs around New Zealand, and international swimmers from Australia and New Caledonia competing in the country's most prestigious synchronised swimming event.
Tauranga Synchro head coach Lara Teixeira Cianciarulo says synchro is a difficult sport, but highly rewarding because of it.
"Synchro a very much a growing sport in New Zealand ... and you can certainly see that from the numbers at this year's competition. It was bigger and tougher," she says.
"Mastering all the components of synchro requires a high level of commitment, teamwork and practice. It was very satisfying to see our girls really improve on all their skills and step up and I couldn't be more proud."
Athletes Eva Morris, Isobel Pettit and Eden Worsley dominated the Junior and Senior categories, winning golds for every solo and duet event they swam in, and the Senior, Junior and 13/14/15 athletes joined forces in the Open Free team event, winning silver with their superhero-themed performance.
Ella Claydon and Chloe Boyt scored silver for their duet in the mixed age Aquarinas category, and together with Amelia Stoutenburg, Sophie Winters and Ella Paterson won gold for their offbeat Willy Wonka routine.
