Hadebe has signed a two-year-deal with an option of a third year.
Last week the 26 year-old surprisingly terminated his contract at Golden Arrows after falling out with the club’s technical team but will now begin the new season with Dikwena.
The left-footed midfielder will provide the wing options for the club following the departure of Thuso Phala.
Meanwhile, Stars will today also complete the signing of Mduduzi Nyanda.
Nyanda will return for his third spell at the club after being transfer-listed by Bloemfontein Celtic.
The 23 year-old has already had two spells at Stars both of which were loan deals while he was still contracted to Orlando Pirates and he is now looking to have his third spell with Dikwena.
Nyanda has been training with Stars since the beginning of the month.
