Germans in Tonga is the culmination of an eight-year research project in which the author and his team of researchers gathered biographical material on Germans in Tonga. There are four main sources: the British Consul Tonga files, held in the Western Pacific Archives of the University of Auckland Library Special Collections; the Defence Department Enemy Aliens files and Aliens Records held at Archives New Zealand in Wellington; the Archives of the German Foreign Office (Auswärtiges Amt) in Berlin; and the Ministry of Justice Archives in Nuku'alofa, Tonga. The volume contains short biographies of over 350 Germans in Tonga born over a 110-year period between 1822 and 1932 and features an introduction by the author on the historical background to the German connection with Tonga.
