NAB has now claimed that during the course of investigations the bureau has "collected some fresh evidences" related to these two cases.
Earlier in the day, the bureau filed supplementary references against Sharif and his sons - Hussain and Hassan Nawaz - in Al-Azizia Steel Mills and Flagship Investment cases.
Interior ministry's response has come hours after NAB wrote to the department to have the three accused in corruption references listed in ECL on alleged possibility of fleeing the country ahead of accountability court's verdict.
The bureau's request to place Sharif and members of his family on the Exit Control List (ECL) comes on the heels of their application seeking exemption from appearance before an accountability court to travel to London.
The National Accountability Court (NAB) on Wednesday filed two supplementarily references concerning Al-Azizia Steel Mills and Flagship investments in an accountability court, DawnNews reported.
New evidences gathered against the Sharif family have been made a part of the supplementary references.
The Spokesperson PTI said that Pakistan's biggest misery is corruption.
Mr Sharif among the three accused are attending hearings of courts with consistency.
Tallal further said that the issue would be reviewed to see if it aims to target a person or is permitted by the law.
Sharif and some of his family members are facing charges relating to their ownership of posh properties in London.
Sharif also took a swipe at courts for failing to bring back to the country former military ruler Pervez Musharraf, who is living in Dubai by dodging several cases against him.
A five-member bench of the Supreme Court on July 28 had directed NAB to file references against Nawaz and his children in six weeks in the accountability court and directed the trial court to decide the references within six months. In January, a supplementary reference was filed against Sharif and four others in the Avenfield properties case.
