A member of the Utuhina Badminton Club, Ainsley said she was feeling in good shape ahead of the intense week of competition, despite a niggling injury.
"I've got a bit of a sore leg but I've been to the physio and it's getting better."
The Northern Region team is one of the favourites for the title, having won the trophy 20 times in the last 29 years. It's a record Ainsley wants to help maintain.
"To win the teams tournament and come home with a gold medal would be nice."
Ainsley said she had no firm goal for the Australasian championships, where she will contest the singles, doubles and mixed doubles. She said her best chance may come in the mixed doubles where she will partner Auckland's Vivian Washington.
A Bay of Plenty representative since the under 12s Ainsley is in her first season with the senior provincial side, where she recently found herself playing doubles alongside mum Lisa Ainsley.
It was an experience neither are in a hurry to repeat.
"It doesn't work well, it's not good," Ainsley laughed. "I can't play with Mum, she has a different style of play to me."
As for who wins the mother-daughter battle?
"It's tight," Ainsley said. "I have played against her once but she managed to beat me ... just."
Mrs Ainsley said her family were grateful to the Utuhina and Rotorua badminton clubs who provided financial support towards her daughter's trip.
