If he awoke it during the battle, then how come it hasn't been brought up since? Luffy awoke his during the fight with Motobaro, then again against Hancock's sisters. The next time he awoke it was in impel down. Zoro has yet to use it again. I know they are different types, but still, Luffy used his unknowingly all within about 40-50 chapters of each other, while it's been about 400 chapters since Zoro allegedly used his. Until he cuts Kizaru, or the equivalent, then I won't believe he has haki. Too inconsistent. One possible time doesn't count.
