Wednesday loaned Lavery out to the League One side at the start of the year and the move was extended until the end of the season earlier this week.
It means that questions have been asked over his future at Hillsborough, but Lavery insists that he is only at Chesterfield as Wednesday want him to get some competitive action.
"They just want me to play games and continue what I'm doing at the minute," he said. "I missed the first half of the season through injury so I've not played a lot of games this season.
"Chesterfield have given me the opportunity to stay and Sheffield Wednesday have allowed me to stay out so I'll try and play more games and we'll see what happens from there."
Lavery missed much of the initial part of the season with injury and so the opportunity to make his comeback away from his parent club has been a good chance for the 22-year-old.
The Northern Ireland youth international is still highly regarded by the Owls, but it seems that Stuart Gray felt he needed to get up to speed again before breaking into their starting line-up.
Lavery's time at Chesterfield has already been productive, as the forward has notched three times in his first seven games.
Lavery has been required to fill the huge void that Eoin Doyle's departure left for the Spireites, but he has made an admirable start and if he continues to hit the back of the net with regularity it is likely that Wednesday will utilise him themselves next term.
