100 years since NZ captured the German colony of Western Samoa

On 29 August 1914, in what was NZ troops' first action during WW1, a 1374-strong "Advance Party NZEF" captured German Samoa, for details see the book Voyage to Gallipoli.

NZ continued to rule Western Samoa until 1962 and as a result there are many Samoans in NZ today. In the 1930s, the Nazis made a big issue of the loss of Germany's former colonies, although this was almost certainly for political purposes and in reality it's unlikely they cared about them; grabbing territory in the east of Europe was Hitler's objective.

Nevertheless, there is the question why Western Samoa wasn't given to the USA after the war which would have made more sense considering America already had the eastern islands which remain an American territory.
