Prior to the First World War, Samoa was a colony of the German Empire. German colonies used the flag of the Imperial Colonial Office, a black-white-red tricolour defaced with the Imperial Eagle. The Imperial German government intended to introduce specific flags for the colonies (also based on the tricolour) and several proposals were created, but the war and the subsequent loss of all overseas territories prevented their official adoption. New Zealand occupied German Samoa in 1914 and officially gained control of the territory in 1919.
From the capture by New Zealand forces on 29 August 1914, a defaced ensign with three palm trees encircled, and emblazoned on the fly were used.
