Twelve jurors heard graphic details of the last hours of her life and deliberated for three-and-a-half hours before returning unanimous guilty verdicts.
Speaking outside court, Pairama's mother Lena Hetaraka-Pairama said it was difficult to sit through the court proceedings.
"It's been tough. She didn't deserve that, none of that. She never even fought with her siblings, let alone get a hiding off someone else or tortured by other people."
"It's been hard for Lena and all of us really, looking at right down to the ... all the evidence of what they done to her and torture her that long and for the hurt that she went through."
Winter and Te Amo pointed the finger at one another during the trial but in end, the jury found they were both guilty.
At the start of the trial, Justice Brewer warned the jurors about the details they would hear in the trial.
After the verdicts were delivered yesterday afternoon, he said the court had a 24/7 counselling service available and encouraged them to use it if they needed support.
"Mr Foreman, members of the jury, it's a difficult job you have had to do. The circumstances you have had to listen to have been difficult to say the least."
Winter and Te Amo will be sentenced on November 5 for murder and kidnapping charges they earlier pleaded guilty too.
