Qian Xun Xue's half-sister Grace Xue has set up a trust in honour of the toddler, abandoned at a Melbourne train station after her mother was killed.
The Little Pumpkin Trust has been set up to secure the financial future of Qian Xun after her mother's body was found in the boot of the family car last week.
Any money left over would be put towards other children abandoned because their parents were involved in crime or accidents, said Ms Xue.
"I would like to think that the people of Australia and New Zealand will help us to create a foundation that will be there helping many other little Pumpkins years from now," she said.
A tearful Ms Xue made the announcement in front of a media-packed inner-city hotel room in Auckland this afternoon.
She said the images of the little abandoned child at the railway station were moving but it wasn't until she saw her father's face - the fugitive believed to be in the US - that she knew she had a half-sister.
Ms Xue said she is yet to meet her half-sister Qian Xun or the toddler's grandmother Xiao Ping Liu who flew into the country yesterday.
"She does not need any more traumatic news at this stage," Ms Xue said.
She said she has been in touch with CYFs to organise a meeting with the Grandmother.
"The poor lady has gone through a great loss," Ms Xue said.
She said when she heard Mrs Liu wanted to adopt Qian, she was happy to hear that Qian Xun had close relatives who loved her.
Ms Xue also gave details of how she too was abandoned by her father Nai Yin Xue. Her story is in stark contrast of a film Mr Xue made with the help of Unitec students appealing to Grace to come home.
"I did not run away from home. I was abandoned in a similar situation. I came to New Zealand, hoping for a better life. It was a big shock for me, after arriving in New Zealand, I was left alone," Ms Xue said.
But she is philosophical about the future, saying the last two weeks have been a roller-coaster ride and that with hard work, you can come back from anything.
Ms Xue also had a message for her father - to turn himself in.
When asked if she would see him again, she said: "If it was my own decision and it would not effect anybody else, I would not try and see him but that was before the incident.
"He might need some support to overcome... might need support to contact the police," Ms Xue said.
She said considering the events of last week, she is "doing well".
"I'm spending a lot of time with my son, he is my absolute top priority," Ms Xue said.
