Several suppression orders prevent the Herald from revealing further explicit details about the killing, which occurred in South Auckland last year.
The suppressions orders, however, will be revisited at a hearing later this year after Justice Duffy told the court significant issues of public importance were raised during the trial.

The father, who was in his 40s, was stabbed six times, including to the head and the fatal strike to his chest.
A 27cm-long knife, with a 14cm blade, was plunged 11cm deep into his body during the short but violent confrontation, the trial heard.
The knife nicked the right lung and penetrated the father's heart.
The accused, who is in his 20s, relied on a self-defence claim, with his defence team, led by Denise Wallwork describing the father as "a monster" who "terrorised his family, both emotionally and physically".
On the night of the killing, the father had seriously assaulted his wife, punching her several times to the face and kicking her.
Her wounds were so severe that one of her eyes had become dislodged from its socket.
She fled to her son's home but the father soon followed and began yelling at his family from outside the home, which had its doors locked and curtains drawn.
The son's partner called police, however, before officers arrived he left the relative safety of the home clutching a knife and checking if his father had left.
"That's why I grabbed the knife, because if I go out there [with nothing] he's going to give me a big hiding," the accused explained in his police interview.
"Seeing my mum, I knew what he was going to do to me he would do to her, that's why I grabbed the knife."
