On May 1, 1931, the "AO" was founded on the initiative of Reich Organization Leader (German: Reichsorganisationsleiter) Gregor Strasser, and its management was assigned to Hans Nieland, who resigned from office on May 8, 1933, because he had become head of the Hamburg police authority; he was replaced by Ernst Wilhelm Bohle.

The local NSDAP/AO delegation in Costa Rica existed in the 1930s to 1940s, numbered 66 members, and lobbied for Germany during World War II.

A branch of the Hitler Youth was created led by the director of the German School Hannes Ihring, but had problems being implemented due to the constant questioning of its participants.

[4] One of the leaders, Max Effinger, was appointed immigration advisor in the government of León Cortés Castro (1936–1940), thus preventing the entry of many Polish Jews fleeing Germany.

[5] By the early 1940s, the NSDAP/AO had perhaps around 50 active members in the Dominican Republic, a relatively large number considering that the German-born population in the country stood at around 150 with an additional 300 persons of German descent.

The Party had organized groups in five Dominican cities: Santo Domingo, Puerto Plata, Montecristi, Cibao Valley and San Pedro de Macorís.

In the mid-1930s, the NSDAP's Finnish country district (Landeskreis) was established, under which, in addition to the Helsinki local group, at least Ortsgruppe Turku and Stützpunkt Tampere operated.

[8] Ireland/Éire (known as the Irish Free State until 1937) was neutral during the war (Northern Ireland was and is part of the United Kingdom), and several Germans and Austrians in the country were active in NSDAP/AO.

[9] Adolf Mahr, director of the National Museum of Ireland, was also Ortsgruppenleiter of the local Nazi party until 1939; he was succeeded by Heinz Mecking, who was head of the Turf Development Board.
