Harry, 24, joins from Billingham Synthonia and scored us against us in our 5-1 victory over Synners in the Tony Lee Memorial Cup match a fortnight ago.
He also bagged a double on his full debut for Town against Great Ayton on Saturday. "I can play as a No10 or on the wing and love to get forward," he says.
"I know Jamie Poole and Anth Lee and Northallerton feels a really good fit for me. I'm looking forward to playing in the First Division and I'm confident I can make the step up.
"Northallerton are a really good club with their own ground and I can't wait for the season to start."
Manager Jamie says: "Harry is a great young talent and someone I’ve watched and loved last season. He’s technically brilliant and will chip in with a fair amount of goals this season. I'm delighted he’s chosen to sign for us."
