In April, she started a charity with a Facebook page called Starlit HOPE.
This has enabled her to deliver, often in person, hundreds of presents - fox monkeys, loom bands, books, nibbles and balloons - to children in oncology wards.
"She is fulfilling her dream of doing a random act of kindness to all the oncology ward kids", said her mother, Sarah Devine, of New Plymouth.
"She has been very particular in picking the presents, packing them in boxes at home and sending them all away."
This has been achieved despite the appearance of another tumour late last year.
The tumour affected her walking - she now uses a frame at home and a wheelchair outdoors - but could not slow her interest in giving.
"She has an amazing determination," said Mrs Devine.
"Lately, when she has been feeling unwell she will come up with an idea and her dad and I will help box it up and she will lie there watching us and then take over to do the finishing touches.
"She loves doing it ... says it takes her mind off the treatment.
"But she has a passion for children and wants to be a play specialist teacher at Starship or New Plymouth hospitals."
Donations and gift-shopping discounts help to pay for random acts of kindness, which include providing Christmas Day breakfasts for parents at Starship children's hospital in Auckland.
"One time she heard a man swearing at staff and thought they did not get much recognition, so for Valentine's Day she sent shortbread hearts to the parents and staff too."
Ewing's sarcoma
• A rare type of cancer.
• Small tumours are typically found in the bones, and less often the soft tissue.
• It is more common in children and adolescents, though adults do occasionally get it.
• The cancer particularly arises in the long bones and the pelvis.
• It does not run in the family.
• It was discovered by cancer pathologist James Ewing more than 90 years ago.
