"He gave me an undertaking he would 'keep a close eye' on Murray and he clearly did not. He said he was satisfied that Nigel Murray was the best person for the job."
Moroney and Association of Salaried Medical Specialists executive director Ian Powell both told Simcock at the time they were worried about Murray because of bitter salary negotiations with doctors in 2007 of which Murray took the lead for district health boards.
Simcock previously told the Herald the concerns raised with him were not relevant to Murray's appointment as chief executive and that he extensively and personally checked Murray's references in Canada where he was the head of Fraser Health before returning to New Zealand.
Yesterday, in answer to the criticism and call to stand down, Simcock said in a statement that he took immediate action as soon as the issues over Murray's expenses were raised with him.
"The board have followed the correct process and procedures to independently investigate this matter," Simcock said.
"The board is satisfied that they have acted responsibly and quickly to resolve this."
A DHB spokeswoman said the board would not make a complaint to police over Murray's expenses because legal advice was that it was not a criminal matter.
She confirmed Murray would not receive any pay-out, but the Herald understands his leave since July 22 was paid.
Meanwhile State Services Commissioner Peter Hughes said he had not seen the report but expected senior leaders of Government agencies to "demonstrate the highest standards of integrity and conduct at all times, especially in relation to taxpayers' money".
Ministry of Health director general of health Chai Chuah said the investigation was an employment matter for the DHB.
He added: "People working in publicly funded health agencies are expected to always act with the utmost integrity".
Murray's resignation is effective immediately and the DHB is now looking to replace him as soon as possible.
Some of his more controversial projects include an unfinished $14.7 million refurbishment of an office building to house 800 DHB staff, the DHB's partnership with the University of Waikato to build a medical school in Hamilton, and a two-year trial of a virtual health model known as SmartHealth.
SmartHealth, thought to cost $17 million, has not yet attracted the targeted number of users and has come under intense scrutiny from GPs who previously said they already had a better, more functional model.
