The 21-year-old, who joined The Citizens from League Two club Accrington Stanley in June 2017, will remain with the club until the summer of 2019.
Wall has impressed with 5 goals in his 20 full JD WPL appearances for The Citizens so far this season, including a brace of goals and two assists in the 5-0 defeat of Bala Town in late November.
Unsurprisingly, his performances has generated interest from other clubs and two bids have been rejected by the Bangor City FC management team, and Luke has now committed his immediate future to The Citizens.
