Mr Pilditch said it was a great relief to hear the guilty verdicts handed down to brothers Wiremu Curtis, 19, and Michael Curtis, 22, as well as the guilty verdict for the charge of manslaughter against Nia's mother, Lisa Kuka, 35.
"Obviously no one takes great pleasure in a trial involving the death of a three-year-old child but there was relief to hear those verdicts."
Outside court, Kuka's lawyer Panama Le'au'Anae told TV3 his client was remorseful.
"She's obviously upset about having lost her daughter so that's something she'll have to live with."
There was little reaction from Kuka as she was found guilty of manslaughter.
A date for the five to be sentenced will be set later.
Tuhoe Pearson, brother of Michael Pearson, who was found not guilty of manslaughter said he was going to give his brother a big hug.
"We need to get this out of the way so he can come home."
Michael Pearson and Oriwa Kemp were found not guilty of manslaughter, but Pearson was convicted of assault for wrestling moves on the child.
The Curtis brothers and Kemp were found guilty of spinning the child on a clothesline and the brothers and Pearson were found guilty of wilful ill-treatment by putting her in a tumbledryer.
With regard to the Curtis brothers, Tuhoe Pearson said he hoped they were locked up and the keys thrown away.
Trial witness Rawhiti Simiona, a neighbour to the house where Nia suffered, told TVNZ he regretted not calling the police when he saw the toddler being swung on the clothes line.
"I feel partially responsible in some sense, that maybe she'd still be alive if I had've rung the police that day 'cause not too long after that she passed away."
Over the past month the court heard details of abuse suffered by Nia in the months before her death.
Wiremu Curtis, who had been in a relationship with Kuka, 35, and his brother Michael Curtis, 22, had pleaded not guilty to murder.
Kuka, Michael Curtis's partner Kemp, 18, and Nia's cousin Pearson, 20, had pleaded not guilty to manslaughter.
All but Kuka were also accused of multiple, less serious offences.
The Crown alleged Nia suffered months of abuse at the hands of the accused but it was the Curtis brothers who delivered the fatal attack, kicking her in the head on the evening of July 20 last year.
The five last week declined to give evidence in their own defence.
