Surrounded by rugged peaks and beautiful lakes of the Waitaki Valley, the earliest inhabitants of the area were Māori on hunting expeditions or travelling through the valley to reach the inland areas and mountain passes.

ECNZ's successors' presence is now minimal as the dams are operated by remote control, and Otematata is becoming a village of holiday homes.

It is a popular holiday destination with a hotel, restaurant, camping ground, backpackers, and other basic services.

Like many inland areas, Otematata has weather that ranges from very cold in winter to very hot in summer.

Although some people chose not to answer the census's question about religious affiliation, 49.2% had no religion, 44.3% were Christian, and 1.6% were Buddhist.
