Mayne was part of Freo's leadership group in 2011, but was overlooked last season.
Pavlich said Mayne had earned his recall after improving his leadership skills.
"We've seen Chris mature as a person and a footballer over the past couple of years, and clearly … the players saw that he has improved in some areas of leadership, and because of his actions he's been voted back in," Pavlich said.
Mayne, 24, said his year out of the leadership group had left him better prepared for his second stint.
"It allowed me to really focus on my game and what was expected of me as a player at this club," Mayne said.
