The 34-year-old former Amakhosi midfielder has signed with Chiefs until the end of the season.
Nale becomes the second high-profile player to join the Eastern Cape side after former Golden Arrows midfielder Musa Bilankulu a few weeks ago.
Bizana boss Nkosinathi Mqokiyana has also confirmed that coach Tshepo Motsoeneng is not going anywhere but staying with the club this season.
"The coach is not going anywhere. I will be doing injustice to the club if I can get rid of the coach," Mqokiyana tells snl24.com/kickoff.
"Tshepo Motsoeneng took us from the village to the town. Since we started our campaign in the GladAfrica Championship we have never had a full squad owing to injuries.
"So if people want me to bring in a new coach, is the new coach going to come onto the soccer field and play?"
Chiefs are set to take on Cape Town All Stars in the Nedbank Cup last 32 in Durban on Thursday.
