The Auckland War Memorial Museum Tāmaki Paenga Hira (or simply the Auckland Museum) is one of New Zealand's most important museums and war memorials. Its collections concentrate on New Zealand history (and especially the history of the Auckland Region), natural history, and military history. The present museum building was constructed in the 1920s in the neo-classicist style, and sits on a grassed plinth (the remains of a dormant volcano) in the Auckland Domain, a large public park close to the Auckland CBD. AK is the index herbariorum code for the Auckland War Memorial Museum.
