"We all know at Newcastle how good he is and he should never have been out of the Argentinian squad," Pardew told nufcTV.
"They've got a new manager and probably that's something to do with it.
"It's difficult for us because he's going to have to do a lot more travelling but on a personal level I'm absolutely delighted for him."
Further games could be added to Coloccini's schedule in the form of Newcastle's upcoming campaign in the Europa League.
Pardew's team qualified for the tournament by finishing in fifth place in the top flight during the 2011-12 campaign.
