Although the two separate provinces are located in one island, they previously formed part of two different regions. Negros Occidental belonged to Central Visayas Region (Region VII) and Negros Oriental was part of the Western Visayas Region (Region VI).

The idea of combining the two provinces into one region begun during the 1980’s when the officials of the two provinces proposed to have one single region for the Negros Island. During that time, it was only Negros Occidental and Negros Oriental provinces in the Philippines that are located in the same island but belonging to two different regions. Being under different regions, both provinces had separate regional offices. The talks regarding the proposal continued up to the early 1990s when the late former Governor Emilio Macias of Negros Oriental and Governor Bitay Lacson of Negros Occidental proposed it once more. However, their efforts were not recognized by the government. The discussion was continued by former Governor George Arnaiz and former Governor Rafael Coscolluella and they designated Kabankalan in Negros Occidental, which is just near Mabinay Municipality of Negros Oriental as the perfect spot for joint regional centers.

The Negros Island Region was again proposed in 2013 by both political divisions claiming that it will be beneficial to both provinces to stay under one region. President Benigno Aquino III directed the DILG to dig further and study the proposal regarding One Negros Island Region. It was on May 29, 2015 that President Benigno Aquino III signed an Executive Order 183 for the effectivity of one Negros Island Region. The Philippines now has 18 regions, Negros Island Region being Region XVIII.

With the new region, Negros provinces will have its own Regional Office so it is now easier for the Negrenses to process documents without traveling far. Also, united efforts between the two provinces can lead to better peace and order, economic growth and development, and acceleration of social development. It is expected that the present set-up will bring efficiency in the government of Negros Island and boost tourism in the area. This movement will also lead to improved planning, administration and management of government policies and programs.
