The New Zealand Transport Agency says it is holding back the $6m until it's satisfied police have met their targets.

The Public Service Commissioner says Coster's role would have been "very, very challenging" if he'd stayed on. Audio

"I am prepared to take responsibility - I got this wrong," the former top cop says as he quits his chief executive job over a damning report into the McSkimming saga.

The man, aged in his 70s, is charged with a serious sexual assault of a woman in Auckland's Onehunga in 1988.

The former Police Commissioner has quit his CEO role after the police watchdog's damning probe into the Jevon McSkimming case.

It comes amid a Corrections review of a risk assessment tool used in deciding whether prisoners are suitable to share a call, after two suspected murders in nine months.

And the c-word that defined the start of Richard Chambers's tenure.

The Commissioner says he's asked for a "closer look" at the police watchdog's scathing report.

An injunction currently prevents media, police and Oranga Tamariki from publishing certain details related to the case.

Chris de Wattignar has quit his role at the Civil Aviation Authority following the report on police handling of Jevon McSkimming allegations.

Police earlier said former Deputy Police Commissioner Tania Kura and another member of the "wider senior leadership team" visited Jevon McSkimming while he faced charges.

But police said, after reviewing all the available evidence, it did not reach the threshold to prosecute Nathan Boulter.

RNZ earlier revealed several police staff were under investigation, including an officer who has been stood down after inappropriate material was found on a police-issued device.

It was earlier revealed about 120 staff were under investigation after 30,000 alcohol breath tests were "falsely or erroneously recorded".

A "health check" of the police agency had begun following concerns over its workplace culture.

Police say they cannot rule out criminal investigations into the staff.

Tania Kura "seemed surprised" when Commissioner Richard Chambers "saw it as a problem".

The two men went for a "very quick swim" in Oriental Bay after an early morning run.

The last time Jung Sup Lee's wife saw him alive was when he 'threw himself' into the flames trying to rescue his son.

Former Police Commissioner Andrew Coster was placed on leave from his role as chief executive of the Social Investment Agency, following the report released on Tuesday.
