Lupoli grabs a point~for Canaries
Ross McCormack netted on three minutes when he turned Dejan Stefanovic before firing past David Marshall.
Norwich were handed a golden chance to equalise five minutes later when Joe Ledley fouled Matty Pattison inside the box, but Jamie Cureton rolled his spot-kick wide.
McCormack doubled the lead with a 67th-minute penalty after he was felled by John Kennedy and drove home the spot-kick.
Lupoli came on with 17 minutes left and took just four minutes to score.
A corner was only half cleared and, when Lee Croft drove the ball back into the area, Lupoli stabbed in.
The striker then netted on 81 minutes when another cross from Croft was headed across Tom Heaton to claim a point.
