The England international was signed from Shrewsbury Town in 2006, with the right-back arriving two years later after spending three years at Espanyol.
The pair, along with club captain Vincent Kompany, are City's three longest serving players and Hart reflected on their time together ahead of Sunday's FA Cup clash with Chelsea.
"I was here first, then Vinny came charging through the door and about two weeks later Zaba came," he said on Sky Sports.
"I was told they were both central midfielders! I’ve seen Zaba age, that’s how long we’ve been together.
"But it’s good that we’ve been together this long and I think we need to be here. We need to be a part of it.

"And Zaba has looked after the Latinos and Spanish. So they’ve got the harder jobs because I’ve just got one or two people to look after.
"I think it’s nice to have us as bedrocks."
The trio are the only players at the club that have survived the entire reign of the Abu Dhabi United Group - which began in 2008 - and Hart does not want the journey to finish any time soon.
"I want to be here for as long as I can," he added.
"I want to be remembered as someone who loved this club and loved playing for this club.
"Someone who appreciated everything the club gave him and gave back everything physically possible that I could give."
