He said he was committed to making the club stronger and hopes to be a one-club player.
He said he was committed to what he described as his "family".
"I’m really enjoying it here and I feel really settled," Boak said.
"[That] definitely helps my footy, probably last year was up there as my best year of footy and I just felt really comfortable.
"But just the group has been so supportive of each other ... and I think the key part of being happy and settled is just the family atmosphere of this club.
"I'm a part of this club and a part of this family."
Boak will be 30 when his new contract expires and said he wanted to finish his career as a one-club player.
Before he even thinks about another deal though, Boak hoped the Power would experience significant success.
Despite a sensational 2013 season, he said his teammates weren't content and wanted to push deeper into the finals in 2014 and beyond.
"We've got the group now to go forward ... we achieved a fair bit last year but it's not enough," he said.
"The exciting thing is that this group is not happy with that, they're not happy with where we finished last year – they want to go further.
"They've shown that already this pre-season [with] the way they've trained, the way they've rocked up, the way they trained in Dubai."
