The man, aged in his early 30s, was charged on Tuesday with driving with excess blood alcohol, dangerous driving and driving while forbidden, serious crash investigator Constable Amie Manning said.
An evidential blood test showed the man's blood-alcohol level was 135mg, almost three times the legal limit of 50mg.
Others involved in the matter could yet face charges and Child, Youth and Family were involved, Const Manning said.
The car the man was allegedly driving flipped, with three children aged between 6 and 9 in the back seat and a female passenger in the front seat, after its driver failed to negotiate a left-hand bend in Easther Cr in the southern Dunedin suburb of Kew on October 8.
The car crossed the centre line, ploughed through a wooden fence and hit its concrete block base with such force the fence was torn from its foundations.
Beer bottles littered the ground around the smashed driver's window and blood pooled around shattered glass strewn on the tarseal.
The man suffered serious injuries and one child sustained minor injuries.
The man was summonsed to appear in the Dunedin District Court on November 27.
