Abdel Razzak had to be carried on a chair in agony for two months to reach Lebanon after he was shot in the abdomen in Syria's civil war.
The home he shared with extended family in the Damascus suburb of Ghouta was destroyed by a bomb in the same 2014 attack.
His wife was pregnant at the time with their second son Moner, now 18 months old.
His father, Mahmoud, lost all but three of his teeth. The remaining three teeth have been taken out since the family arrived at the Mangere refugee centre last week in the first group of 82 Syrians under a Government policy to take 600 extra Syrians on top of New Zealand's annual quota of 750 refugees.
In the midst of the Syrian war, there was no way to get to a hospital.
