The under-fire official confirmed he will meet again with the Dáil’s public accounts committee in April after the HSE has concluded a major report into the group’s financial practices.
In a letter to the cross-party political group sent by his solicitor, Mr Kiely said he is willing to submit to further questioning on the sheer scale of the pay-outs he received.
Before the board of the CRC was forced by the HSE to resign on masse last December, Mr Kiely and other now ousted managers from the group had attempted to defend the financial issues to the PAC.
The former chief executive and close confidante of ex-taoiseach Bertie Ahern told the cross-party group at the time he was in receipt of a €106,000 salary.
However, it emerged the figure was 242,000 — €136,000 of which was coming from money donated by the public for frontline services.
Mr Kiely also claimed his retirement package when he left in 2012 consisted of a €200,000 lump sum pay off and an annual pension of €98,000.
However, last month the HSE confirmed that the payments consisted of a €200,000 tax-free lump sum, a €273,336 taxable amount and a further €268,689 — bringing the rate to €742,025.
A significant proportion of this figure was coming directly from charitable money donated by the public which was meant to be specifically ring-fenced for frontline services.
The extent of the alleged misuse of charitable money and the individuals involved is now at the centre of a major report by the HSE’s interim administrator for the CRC, John Cregan.
This document, which could lead to fraud charges being made, is likely to be concluded by mid-April.
Among the other issues it will play a role in uncovering is a €20m gap between the amount of money donated to linked group the Friends and Supporters of the CRC and the amount transferred to the CRC or any of its other subsidiaries between 1998 and 2011.
Meanwhile, PAC chair and Fianna Fáil TD, John McGuinness, has told the separate Rehab group it must reveal all details of salaries, pensions, bonuses and other allowances to the cross-party body when it meets next Thursday.
On Monday, Rehab said its chief executive, Angela Kerins, receives a €272,400 pay packet — including a €240,000 basic salary, up from €234,000 in 2011 — to run the disability charity.
It refused to reveal the rates of pay for other top executives. Mr McGuinness said he considers this position a “holding statement” and will insist all details are made public.
Separately, the HSE has confirmed it is giving St Vincent’s Hospital an extra month to remove top-ups for managers.
