I sent an email to NH f&g and got this response:

"I believe it does not meet the definition of Fly fishing. In the digest page 8. https://www.wildlife.state.nh.us/fishing/publications.html".

Fly-fishing: Fishing by trolling or casting with only fly rod, fly reel, and fly line combination with an artificial fly or cast of artificial flies attached, and does not include the use of spinning, spincast, and casting rods and reels and lead core lines.
