Provinces of Solomon Islands from Tulagi to Honiara. At its independence in 1978, the protectorate became the sovereign state of Solomon Islands. Honiara continued to function as the capital of the sovereign nation, and the inherited districts and councils remained until 1981, when the nation was reorganised into seven provinces by splitting some of the districts into provinces: the Central District was split into Central, Guadalcanal, and Isabel provinces, while the Eastern District was split into Makira-Ulawa and Temotu provinces.

Population growth was very slow and only about 5% of Solomon Islanders were living in the city. However, the Bellonese population significantly increased; they established permanent and semi-permanent houses in the Honiara vicinity, typically along the banks of the White River. The town was affected by creolisation.
