Netherlands Indies Government Information Service

Conrad Helfrich, commander of Dutch forces in the Netherlands East Indies, attempted to have NIGIS merged with NEFIS, for which he had responsibility.

Helfrich's attempts were resisted by Hubertus van Mook, acting Governor-General of the Dutch East Indies, who wished NIGIS to retain its civil status rather than be absorbed by the military apparatus.

[11] After the end of the war and the surrender of the Japanese, NIGIS turned its focus to asserting Dutch sovereignty over the newly proclaimed independent Indonesia during the Indonesian National Revolution.

NIGIS and its sister agencies claimed that the Netherlands supported Indonesian independence, however promoted the line in Australia that the Republic of Indonesia was a "Quisling Japanese-sponsored government".

[12] When Australian maritime trade unions blockaded the Dutch shipping fleet in Australia in what was called the "Black Armada", NIGIS produced and distributed pamphlets claiming that the supplies to Indonesia were humanitarian in nature, and were not military materiel and personnel intended to suppress the independence movement.
