Elected member Dave Macpherson, who has been vocal on the subject since an investigation was launched by the health board into Dr Murray's spending in July last year, said the pair needed to take responsibility for their actions.
A State Services Commission investigation, released yesterday, found more than half of Dr Murray's expense claims for travel and accommodation, worth $120,000, were unjustified.
State services commissioner Peter Hughes found Dr Murray's actions were "serious and sustained breaches of the state sector code of conduct" and he referred the case to the Serious Fraud Office, which confirmed it is now investigating.
Mr Macpherson said the findings confirmed much of what was found in both the Audit New Zealand review into Dr Murray's expenditure and the board's own investigation.
Dr Murray was a former chief executive of the defunct Southland DHB.
"Nigel Murray was a supposedly experienced public servant in the health sector. He knew what was allowable and what was expected.
"It is completely disingenuous for him to try and claim he is being treated `unfairly'," Mr Macpherson said.
"It is the taxpayers of New Zealand that have been treated unfairly by Nigel Murray, and indeed have been ripped off by him," he added.
He said he had no sympathy for either Dr Murray or Mr Simcock.
"As chair, Simcock had the right and the responsibility to monitor the work and activities of the CEO; the fact that he didn't - and that Murray got away with so much over three years - only demonstrates that Simcock was asleep at the wheel. What is more, there is ample evidence that Simcock was personally warned not once, but twice, before Murray was appointed about the man, his behaviours and the trouble he caused at other health authorities."
He said Mr Simcock should have more closely monitored Dr Murray following the warnings.
Dr Murray and Mr Simcock, through statements released by their lawyers yesterday, hit back at the inquiry, calling it unfair.
Mr Simcock pushed the blame on to Dr Murray, who he said led a double life and misrepresented expenses claims.
Mr Simcock, who resigned on November 28, lambasted the findings, saying the inquiry failed to "properly identify root causes and instead produced a report which is a scattergun of blame".
"Unfortunately I am being held up as a scapegoat for some of what Dr Murray did, when it is now clear he led a double life.
"There was so much dishonesty surrounding Dr Murray that even with professional advice and checking, he was still able to hide his behaviour."
In a letter from Dr Murray's lawyer, Peter Cullen, to inquiry head John Ombler, Dr Murray said he believed the investigation into him was "unfair" and "seriously flawed".
"As you will be aware, from the outset we have raised and continue to raise serious concerns about Mr Ombler's decision not to provide Dr Murray with copies of the information and documents that he has obtained in the course of his investigation and which are relevant to the terms of reference in so far as they relate to Dr Murray."
In the January 19 letter Mr Cullen said there was no doubt about pressure from media and the Government for a "hasty investigation" and result.
"Dr Murray believes that the pressures we refer to are playing a dominant role in this investigation and that his rights are being trammelled."
Mr Cullen said Mr Murray needed fair treatment from the Serious Fraud Office without it being tainted by other inquiries first
