The striker arrived at The Lamex Stadium early in the month and helped Boro to four wins in six games.
He scored on his debut against MK Dons in the JPT, notched twice in the 2-1 win over Brentford and also scored at Walsall, whilst providing experience to Stevenage's frontline.
Zoko picked up 37% of the online vote, beating off Filipe Morais (25%), Simon Heslop (20%) and Chris Day (18%).
Season ticket holders also voted Luke Freeman and Peter Hartley as their Player of the Month for September and August respectively.
Luke played up front against Tranmere and MK Dons as well as putting in decent attacking performances at Preston and against Carlisle. It was his work down the left flank which led to Boro's consolation goal at stadium:mk and he won the penalty against Carlisle which Tansey converted.
New signing Peter Hartley arrived at the club in August, making his debut against Leyton Orient at home. The defender slotted into Boro's defence as if he'd been there for years and helped his new team pick up their first league win of the season at Notts County.
