Mr Torea said he was perplexed as to why Hawea was named as being "homeless" in court and he claimed that he was disappointed that the family were not contacted by police following his arrest.
"Probation Services have first-hand knowledge of his accommodation, bail conditions and supervision so I don't know why the police have said he was homeless?" Mr Torea said.
"The question begs why police didn't make contact with probation and make contact with our family [after his arrest]."
Prior to the death of his grandaunt when he was 17, Hawea was previously described by friends as a promising academic and rugby player.
"He's had no male role-models in his life," Mr Torea said.
"[His grandaunt] struggled greatly with him but she was always there."
Sergeant Garry Wilson of Masterton police said he was unaware that Hawea had been staying with his grandparents and he believed all he needed was a "good adult influence".
"I will have to agree we haven't seen Ben around the streets for a long time," he said.
"There was a period of time [earlier this year] where we were concerned because we knew he was back in town. It's certainly pleasing and it can only be good for him."
Mr Wilson said he believed police had done everything they could for the troubled young man.
He said it was only their job to know where he was when there was a reason to look for him.
"If we've got no reason to go looking for him we're not going to be looking for him," he said.
"If Ben is keeping out of trouble that's fantastic and I would applaud the efforts being taken to deal with him."
Hawea had previously completed 17 terms of imprisonment.
On April 10, he appeared in Wellington District Court in relation to the indecent assault charge and he was bailed, without plea, to his grandparents address on a 24-hour curfew. He is due to appear at Wellington District Court again on April 29.
