Since his contract at the Etihad Stadium expired Barry had been free to talk to other clubs but chose to stay at a team in which he was a key component last season.
Martinez always expected this to be a drawn-out summer in terms of new signings but retaining the services of Barry was near the top of his list of things to get done.
"Gareth is such a unique person, I have been so impressed and I think everyone at the club has taken to him," Martinez said before the deal was announced
"He has been a special player for us... Football happiness is a major aspect any footballer chases and Gareth and Everton are a perfect fit and the way he has been performing shows he has that footballing happiness.
"We all know what Gareth brings and how important that is."
