Kadi scored his eighth goal in the last six games to take his tally for the season to 15 in 24 matches, and leave his team nine points clear in the promotion places with seven matches remaining.
Veria thumped fifth-placed Platanias 5-0 and have now won six of their previous seven matches, with the other game drawn.
However, they face a tough challenge on Sunday when they travel to second-placed Panthrakikos, where a win would be another giant step towards promotion.
Kadi’s goalscoring exploits have drawn interest from across Europe, but it is unlikely that he will make a decision on his future until this season has been completed.
Kadi’s contract with Veria comes to an end in June, having signed a one-year deal with the club after he left Bidvest Wits at the end of the 2010/11 campaign.
