She doesn't really sing yet but she is trying with her left hand to play her ukulele.
"She is playing what she calls clock chimes. She plucks the strings and they really sound like a clock chiming. It's really lovely."
Hannakah has been looking after Rebecca for nearly five years and said the little girl had made amazing physical progress.
She has been top of her class for the past five years at South Makirikiri School and nothing deters her, Hannakah said.
"She is very independent and loves to do things for herself and works very hard at it."
The trust will also help buy special equipment like musical instruments or books.
Even though she was a bit nervous getting on the stage to receive her award, she realised very fast that the people in the crowds were very happy for her, Hannakah said.
Rebecca was diagnosed with cerebral palsy when she was seven months old.
Hannakah said it was years before she would walk on her own and now she's only using her electric wheelchair for long distances.
"She wants to sing and play her ukulele and knowing Rebecca it won't take her too long. She's very determined."
