Since the bike is brand new, you can let the shop check it out for free (should be). Of if you want to eliminate the handlebar/stem possibility mix a small batch of 20:1 petroleum solvent and oil. It should be super thin. Apply to the bar at both sides of the stem clamp and let it wick in. Wait a while and ride. If it solves the problem, you now have both the cause and cure. If it doesn't you can rule out that possibility and focus on others.
Especially if both the bar and stem are aluminum. That combination really loves to creak. Just ask anyone who ever owned a Cinelli 1X stem.
I have a headset that creaks after it has been ridden in the rain. I have to take it apart, dry it off and regrease everything. No more creak.
