He called the tribunal "an Israeli project to create strife in Lebanon".
On Monday, Nasrallah presented evidence that he said showed his arch-foe Israel was behind the February 14, 2005 bombing that killed al-Hariri and 22 others in Beirut.
He said he would not hand the evidence over to the UN tribunal because he did not trust it.
Nasrallah produced several undated clips of aerial views of various areas in Lebanon, including the site of the Hariri assassination in mainly Sunni west Beirut several years prior to the murder.
He said the footage was intercepted from unmanned Israeli surveillance drones.
"Nasrallah has not provided undisputed, solid proof that implicates Israel," Al Jazeera's Rula Amin reporting from Beirut said.
Syrian- and Iranian-backed Hezbollah is facing increasing pressure as the UN-backed tribunal appears set to accuse several of its members.
Nasrallah has said prime minister Saad al-Hariri, the son of Rafiq, vowed he would publicly declare any Hezbollah members indicted were renegades and not disciplined party members.
Al-Hariri's stance is widely viewed as an attempt to avoid violence between his mainly Sunni Muslim supporters and supporters of the Shia Hezbollah at all costs.
'Exit for everyone'
Khalid Saghiyyah, the editor-in-chief of al-Akhbar, wrote in his newspaper that the documents that were presented by Nasrallah "simply say: Yes, it is possible to redirect the accusation towards Israel."
"This alone represents a suitable exit for everyone.
"An exit for the fabricators of false witnesses. An exit for those who are rightfully accused. An exit for those wrongly accused. An exit for the descendants of the victims," Saghiyyah added.
Tribunal president Antonio Cassese has said there is no fixed date for any indictments, which "will depend on when the prosecutor determines there is enough evidence."
The al-Hariri assassination triggered an international outcry and led to the withdrawal of Syrian troops from Lebanon in April 2005 after a deployment of almost three decades.
The murder has been widely blamed on Syria but Damascus has consistently denied involvement.
