For his efforts he collected a $500 credit at the Gat Shack music store.
His 18th birthday is next month and he's been playing music for the last 12 years.
He describes his musical genre as "pop-rock with a hint of the blues".
He played two original songs in the final, one called Crazy sung to a backing track he produced, and the other was Let It Be.
But it was this second number which is special. He wrote so he could still play his guitar even though his lower is arm is in a sling after he broke his left wrist when he fell at the Splash Centre four days before the final.
"There was no chance I was going to pull out because music is my life," he said.
Currently Logan's thinking of heading to Auckland after he leaves school to study audio engineering. It's a one-year course and that could lead to a degree course.
"But whatever happens I'll always be doing my music, whether that's on the professional stage or a local stage. I've got a message to tell and I don't want to restrict who hears that message."
So what is the message?
"It's about getting to know people for who they are. I like to tell stories with my music so I guess it's about telling people that their stories have value, valued by me and by God."
