Paul Tainui was showered with kindness and repaid it by brutally raping and murdering two young women.

The criminal pscyhopath's actions also directly contributed to a third death - the father of one of his victims.

Coronial findings released on Wednesday showed Tainui - who was born Paul Wilson - misled and lied to those trying to help him reintegrate into society, following more than 16 years behind bars.

Tainui was jailed after raping and murdering his former girlfriend Kimberley Schroder in 1994 and was later a groomsman at David Bain's wedding after the pair served time in prison together.

Seven years after his release, Wilson raped and murdered Nicole Tuxford in her Christchurch home on 7 April 2018.

Heartbroken by the news his daughter's murderer had killed again, Gary Schroder took his own life less than 72 hours later.

Following Tuxford's murder, Tainui was identified as a criminal psychopath. However, testing in 2010 ahead of his parole failed to indicate psychopathy and found Tainui a low risk of reoffending.

Coroner Marcus Elliott held a joint inquest into the deaths of Nicole Tuxford and Gary Schroder, finding Corrections failed to identify the acute risk to Tuxford's life at the time of her death because of a systemic issue with the department's processes.

Tainui's risk of reoffending was at its greatest in the context of potential or actual intimate relationships with women.

Coroner Elliott found the Parole Board was aware of that risk when it granted Tainui parole in late 2010.

"The risk assessment process ... correctly identified that Mr Tainui would not reoffend within five years. It correctly identified the particular area of heightened risk. However, it did not identify that he was a criminal psychopath who was at chronic risk of committing extremely callous and brutal crimes even seven years after release," he said.

"The words of Mr and Mrs Schroder to the Parole Board in 2010 proved to be prophetic: We know he will reoffend again, it's just a matter of when."

Tainui's probation officer was also aware of his risk to people he was intimate with or even perceived himself to be in a relationship with, but his employer did not have an appreciation of the
