A Government spokesman has said public service unions and management will be invited to a special meeting "shortly" to discuss further savings under the Croke Park Agreement.
The meeting is not expected to take place this week.
The spokesman said Taoiseach Enda Kenny and Minister for Public Expenditure and Reform Brendan Howlin were still reviewing reports from each Cabinet minister on ways of securing more savings under the agreement.
The spokesman strongly denied that the attempt to find extra savings was a response to the relatively small savings found in allowances.
He said this was "a proactive process" initiated by the Taoiseach, which would see ministers being "innovative".
The spokesman added that the Taoiseach "would not be very happy" if significant savings were not forthcoming.
