"I think what Hospice does is amazing for our whānau and community, and this is my way of doing my part."
Isbister had already pulled several muscles and goes to physio a few times a week, but she said that when you aced a move it was exciting and made you feel good.

Trask and Isbister also wanted to give a special mention to Jess and Denise at Hospice - "They are amazing. For every question they are there and they support us dancers".
