Taitoko was picked up from his brother's house in Manurewa and taken to a suicide prevention cell in the police station.
He died after repeatedly injuring hitting himself against the walls of the cell, where he was being regularly checked by police officers.
An inquiry into his death resumed in the Auckland District Court today after coming to an abrupt halt last October when the Skycity Convention Centre caught fire nearby.
Last year, the coronial inquest heard an officer asked a passing doctor - who cannot be named - for an opinion about Taitoko's state.
The doctor - who has name suppression - advised the young man would be safe in police care if he was monitored regularly.
The doctor told the inquest he was not made aware of the self-harm, and if he had known about it he would have advised the young man be taken to hospital.
This afternoon, Taitoko's family lawyer Barry Wilson asked another doctor if it was normal practice to inquire about a person's behaviour before and during their time in custody.
Dr John Bonning - an experienced police medical officer based in Hamilton - told the inquest it depended on the circumstances.
"If the person was pointed out to you and you were asked to give any form of opinion, verbal or otherwise, even with something as minor as, 'do you think this person is okay?' It depends.
"It depends on how long they've been there and what their condition and behaviour had been like up to that point. Of course you would want to know some more detail."
Last year the court heard the doctor who observed Taitoko that night felt reassured the 21-year-old appeared subdued when he saw him.
Today, Dr John Bonning told the court attitudes towards so-called "corridor consulations" had come a long way since 2014.
"The concept of a casual consultation is something that we would be very careful of. Overall, the safety of persons in custody has been drawn into focus over the years with adverse incidents that have occured on both sides of the Tasman."
Emergency medicine specialist Dr Garry Clearwater later told the inquest quick "corridor consultations" were commonplace in any emergency department.
"That's in the nature of a busy emergency department; a supervising doctor is often asked in passing for a quick opinion. To spend a lot of time formally assessing every patient would seriously impair my ability to get through the workload."
Dr Clearwater said it was entirely feasible Taitoko could have also died had he been restrained and sedated that night.
'It's a terrible dilemma for clinicians about forcibly restraining a patient to sedate them because it carries risk and it's well-recognised that that's often a trigger point for the death of a patient."
Dr Clearwater said there was a known reluctance to admit people with extreme behaviour with emergency departments because of the enormous strain on resources; some aggressive patients requiring up to 10 hospital staff for their care.
Taitoko's whānau have waited more than six years to see his coronial inquest through to the end.
After the SkyCity Convention Centre fire, a nationwide lockdown, and a further three-hour delay this morning to resolve tech issues, the inquest is finally under way again.
It will resume in the Auckland District Court tomorrow morning.
