According to the Express Tribune, shares in six companies owned by Hassan and Hussain Nawaz were ordered frozen.
The court directed the Securities and Exchange Commission of Pakistan (SECP) to freeze these shares after taking into account details presented in a report submitted by NAB prosecutor Afzal Qureshi.
The case will next be heard on November 14.
Non-bailable warrants of arrest were issued for Hassan and Hussain earlier this month for failing to appear before the court.
The references were prepared in light of the July 28 judgement of the Supreme Court in the Panamagate case.
