Like most Eri-Aka towns of Igboland, Ogbunike is divided into three main parts: Ezi, Ifite and Ikenga.
Amawa is part of Ezi, Ifite also names its village and Ikenga hosts Ukalor, Osile, Umueri and Azu.
In 1976, businessman John Ositadimma Umenyiora, son of a Protestant pastor, was unanimously chosen as the first Igwe of the town and given the name Eze-di-ora-mma I.
The Ogbunike Caves — a natural geographical feature located at the periphery of its historical boundaries draw tourists.
According to oral tradition, a god called Ogba lived inside the core of a large rock in the cave.
It was said that a woman undergoing menses cannot enter this cave in the olden days (prior to British East Africa) as they were unclean.
