But they have only until today to tell funeral directors whether they will be able to pay for her flight home.
"We are trying to do everything we can do and put it out there to the rest of the family that we need financial assistance," she said.
"But at this time of the year, nobody is in a financial position to come up with the money."
Ms Samuels' body stayed in Eagleby with family last night and Ms Winter said funeral directors due at the house this morning needed to know whether she would be kept in the country.
"They need to start making the preparations for the flight and we've pretty much told everyone that if it's not possible to come up with the money, we are just going to have to leave her there."
Ms Samuels' mother, Susan Opai, had not been able to see her daughter until Tuesday - two days after she arrived in the country, she said.
The rest of the family had been left "devastated" after being phoned with the news early on Sunday morning.
The tragedy came three months after Ms Samuels gave birth to her fourth child, Cassius, in August.
Her other children - daughter Portia, 3, and sons Sentorri, 4, and Tipene, 6 - had begun asking where their mother was, Ms Winter said.
A "south-side girl and very proud of it", Ms Samuels left Mangere for Queensland shortly after finishing high school.
She switched jobs "like the weather" while raising her children, before settling down as a full-time caregiver, Ms Winter said.
"She was a very bubbly person, full of life, and was always cracking a joke and sharing the love with everybody.
"You could definitely say her kids were very well taken care of.
"She was an amazing mother and the kids were always her first priority.
"I think we'll always remember her as a loving, pure, honest person who would do anything for anybody at the drop of a hat, that was our Emily."
Ms Winter said the family would keep trying to meet the costs until the last minute - and would even look to the community if they had to.
