As a rhetorical evocation of a New Zealand national identity, Zealandia appeared on postage stamps, posters, cartoons, war memorials, and New Zealand government publications most commonly during the first half of the 20th century. The personification was a commonly used symbol of the New Zealand Centennial Exhibition, which was held in Wellington in 1939 and 1940. Two large Zealandia statues serve as war memorials that honour the casualties of the Second Boer War: one is in Waimate and the other is in Palmerston. Some smaller statues exist in museums and in private hands.
