According to the Football411 website, the former Sundowns man joined Amakhosi in 2009 and has gone on to make 118 appearances, scoring 12 goals in the process.
Dladla told the club's official website: "I am excited with the contract extension and looking forward to the start of the 2013/14 season. I just want to thank the club for believing in me and that I can still make a contribution in the success of the Team going forward."
Chiefs' football manager Bobby Motaung says he is delighted with the 33-year-old's decision to extend his stay with the Glamour Boys.
"We are happy to have Josta remaining on board. The coach will utilise him as a utility player and his experience will still be invaluable in what is going to be a tough season of defending the league title. We would like to wish him luck in the season ahead," he said.
