Aircraft; Procedure
On a practice approach for the RNAV into ZZZ; a pilot in Aircraft Y made a radio call he was holding at Runway XY and said please advise if there is traffic in the area. Aircraft Z on an 8 mile final for [Runway] XX; also on the practice approach; made immediately a position report and we did ours right after. We reported a one mile final for Runway XX. My Student was flying under a view limiting device and had no visual reference outside. Visibility was 4 miles; haze and smoke so it was hard to see where that airplane was. When I was scanning for that traffic; he appeared right in front of me; airborne; almost same altitude heading straight toward us. I took the controls of the helicopter immediately and did a steep right turn to avoid a midair collision. I made a radio call and said we all would appreciate if he would make a radio call prior to take off. The pilot in Aircraft Y said he wasn't aware of us and said we never did a radio call. However I talked with the pilot in Aircraft Z behind us and he confirmed our radio calls and knew exactly where we were.
Helicopter instructor pilot reported a NMAC in the traffic pattern due to an aircraft departing in the opposite direction.
