This ceremony commemorates all New Zealanders killed in war and also honours returned servicemen and women.
The date itself marks the anniversary of the landing of New Zealand and Australian soldiers - the Anzacs - on the Gallipoli Peninsula in 1915. The aim was to capture the Dardanelles, the gateway to the Bosphorus and the Black Sea. At the end of the campaign, Gallipoli was still held by its Turkish defenders.
Thousands lost their lives in the Gallipoli campaign: 87,000 Turks, 44,000 men from France and the British Empire, including 8500 Australians. Among the dead were 2779 New Zealanders, about a fifth of those who served on Gallipoli.
It may have led to a military defeat, but for many New Zealanders then and since, the Gallipoli landings meant the beginning of something else - a feeling that New Zealand had a role as a distinct nation, even as it fought on the other side of the world in the name of the British Empire.
