Ceena Ngaronga, 2, died at the Sydney's Westmead Children's Hospital afterbattling a rare virus.
The youngster was diagosed with hemophagocytic lymphohistiocytosis (HLH), which causes the immune system to turn against itself and damage the patient's own tissues and organs. It was discovered after she was admitted to hospital last November.
Ceena was rushed to hospital in a critical condition where doctors told her parents, Masterton-born Dominique Ngaronga and his partner Cecile Raymundo, she would need an urgent liver transplant.
Her aunt, mother-of-two and fellow Kiwi Lacoya Finau, was a perfect match and, in an operation that took around eight hours, she donated a quarter of her liver to the little girl.
Following the transplant Ceena, who was born in Australia but whose family said was very much a Kiwi child, began showing signs of improvement and her family hoped she would recover. But her condition began deteriorating and she died on December 11.
