Sinn Féin has called for a detailed review of NAMA's loan book to ensure the agency is bringing maximum value to Irish citizens.
The party’s Junior Finance Spokesman Peadar Tóibín claims the Government is pursuing a fire-sale strategy by setting a wind-up date for NAMA of 2018.
Mr Tóibín argues that private companies are buying assets from NAMA and securing significant sums of additional profit in very short periods of time.
He says this problem, coupled with an absence of transparency, means the entire loan book from the agency needs to be reviewed.
He described the 2018 wind-up date for NAMA as "arbitrary" and contended, if pursued, would amount to a "fire-sale strategy".
Meanwhile, the Chair of Stormont's Finance Committee, Sinn Féin MLA Daithí McKay, has also criticised Minister for Finance Michael Noonan over NAMA.
He claimed the minister failed to quickly respond to a request for assistance from Stormont in getting NAMA to attend headings into allegations that millions of pounds from the purchase of NAMA's Northern Ireland property portfolio had been earmarked for a politician.
However, the Department of Finance has rejected criticism from Sinn Féin.
It said it received a letter from the Stormont Finance Committee on 20 July, and sent a hardcopy reply on 23 July.
The department added that an electronic copy of its response had been sent onto the committee only today.
