The family of 22-year-old Yamatji woman Ms Dhu, who died in police custody in 2014, has renewed calls for CCTV footage of her final hours to be publically released.

Their plea followed an ABC Four Corners program that revealed severe mistreatment of teenage boys at the Don Dale Detention Centre in the Northern Territory, sparking a royal commission into the centre.

Ms Dhu died after being taken into custody at the South Hedland Police Station in August 2014 for non-payment of fines totalling $3,622.

She was taken to hospital three times in the space of 48 hours, and died on her final visit.

A post-mortem examination found the cause of death to be septicaemia and pneumonia resulting from an infection from a broken rib.

A public inquest into the young woman's death held earlier this year was shown footage taken from security cameras at the police station and hospital of Ms Dhu's final moments.

On the final day of the four-week inquest, coroner Ros Fogliani ruled releasing the footage into the public domain could cause further trauma and distress to Ms Dhu's family.

Although the family at the time said it wanted the footage released, the coroner said the privacy of the young woman outweighed the public interest.

Family wants 'truth and accountability'

But following the broadcast of the Four Corner program on abuse of boys at the NT detention centre, Ms Dhu's family has renewed its calls to release the CCTV vision.

Her uncle Shaun Harris said on Tuesday the public had a right to view the footage and believed, like the response to the Don Dale footage, it would elicit change.

"It's traumatising yes, but it still needs to be put out there," he said.

"They can't hurt us anymore, but they can traumatise us more by still holding back the truth.

"There will never be any justice unless there is truth and accountability.

"The footage of the CCTV release would not be violent or harsh backlash, it would be deserved attention on the whole issue of my niece and black deaths in custody."

Death in Custody Watch Committee spokesman Marc Newhouse said there was absolutely no doubt the footage should be released.

"Ultimately it's about transparency and accountability and when things happen behind closed doors and the records of that are suppressed that's greatly concerning," he said.

"We hope that others in the community demand to see the footage and for that to be released publically."

A spokeswoman for the office of the state coroner said Ms Fogliani made a decision on the release of the footage after hearing legal arguments from all interested parties in open court earlier this year.

She said the coroner's ruling made in March would remain unchanged.

The office for Attorney General Michael Mischin said he was mindful of the State Coroner's ruling and believed Ms Fogliani had made a reasoned decision to not make it publicly available.

It said the Attorney General was not able to ignore or overturn the decision and if an interested party was dissatisfied with the coroner's ruling they should either apply to the coroner or seek a review or appeal of the ruling.

The office said the Attorney General had not seen the footage of Ms Dhu and would wait for the Coroner's findings and comments regarding it.
