Having spent last season with PEC, Tedic will remain for another 12 months after a deal was settled last week.
Tedic said: "I feel at home in Zwolle. I liked both the club and the city last season, despite the fact that I was hardly able to show the real Tedic due to injuries. I can't wait to play with supporters in the stands.
"I have received so much support from the supporters through the socials, among other things, that I can't wait to give back that confidence and that blue and white love through my commitment and performance on the field."
PEC technical chief Mike Willems also said: "I am very satisfied with Slobodan's longer stay. We know his qualities and we know how extremely motivated he is to make a success of his second stay in Zwolle."
