Later that year he was assessed by mental health services, which revealed a five-month history of psychotic symptoms.
These included auditory hallucinations, feeling insects behind his eyes, and fears his food was being poisoned.
From 2009 until his death he was under the care of mental health services, was admitted to inpatient care three times, and was subject to a compulsory treatment order.
He was diagnosed as having a psychotic illness, conduct disorder and substance abuse.
Issues were raised several times about whether he was receiving appropriate care at home, and whether he was taking his medication. He was moved at various times between the care of his mother and father, who were separated, and an aunt.
In the weeks before his death mental health workers were unable to find him to give his fortnightly injection of antipsychotic medication, and he did not attend scheduled assessments.
Family members, however, said his behaviour had been improving, and they were concerned that the antipsychotic drugs were doing more harm than good.
The coroner's finding said she was in no doubt that Nikora had a severe mental illness, that the medication was required and prescribed appropriately, and did not contribute to his death.
She recommended the Ministry of Social development assess CYF practices, and that the Auckland health boards and CYF review their practices when a collaborative response is needed, and when a young person's living arrangements include two DHBs.
The Waitemata District Health Board was also recommended to consider a lower threshold for seeking police assistance in enforcing community treatment orders.
