Topographic Maps of the South Pacific Islands of WWII

I am looking for Topographic Maps of the Solomons, Noumea, Espirito Santos, New Zealand, and the other Islands in the SW Pacific (the Atolls in the Central Pacific are fairly flat, and due to having a sister who works on most of them cataloging endangered wildlife to remove or isolate, I have pictorial evidence that is enough to reconstruct their pre-WWII and WWII configurations).

But the Islands where the Allies fought in 1942 and 43 are principally of interest.

These would be all of the Southern Islands in the Solomons, plus Bougainville; New Guinea including New Britain and New Ireland plus the Manus Islands; the Islands that make up Vanuatu where Espirito Santos was used by the USA as a major Naval Base; New Caledonia, where Noumea was located, from which the war was directed for 1942 and early-1943; Celebes, now Sulawesi, and Borneo, both a part of Indonesia; and the Palaus.
