@Bold, where did you get that from? Any manga scans? I provided a manga scan that showed Iruka is the most influential figure in Naruto's life. Not Zabuza, not Haku , not Sasuke, not Jiraiya... but the very man who saved him from despair, and taught him the basics of being a ninja.
His ninja way is "never give up" "don't go back on my words". All Zabuza and Haku did was show him how other ninja are like, and he chose to be simply not like them. Not denying their influence over him, since he does respect them and all.
Reason why his mom can't be the most influential, is simply due to the reason, they didn't save him from despair, weren't there when he needed people to be by his side.
The dude has always been there.
