We recently spent a few days in Wellington - specifically to explore the Peter Jackson installations regarding NZ at war. The Great War exhibition commemorates the role played by NZ in the First World War. It follows the journey of the war year by year. Never having been very interested in war of any kind, I learned a lot. This exhibition is at the War Memorial Museum (behind the Cenotaph and tomb of the unknown soldier).
The final scene of this exhibition shows the words emblazoned on the wall of the recruitment office to inspire young recruits - underneath are soldiers as they stumble home blinded by mustard gas . Older and younger generations grieve together at the graves of those who died.
The other exhibition Gallipoli: The Scale of Our War is at Te Papa. This web link gives a very good idea of what is included in this exhibition. But nothing compares with seeing it personally. Some of the people featured are "there" in larger-than-life-sized models. (See the size of the doorway on the right to get an idea of scale.)
I wonder what it would be like to be a descendant of one of them walking around and meeting a grandparent or great-grandparent "face to face". Anthea had two great-uncles at Gallipoli - not featured in models but certainly shown and celebrated.
If you visit Pukeahu War Memorial Park (to see The Great War exhibition) you will also see the Australian Memorial which honours the role Australians played in the war.
