Commemorations for the Battle of Passchendaele, New Zealand's greatest tragedy, took place on Thursday.
It's been 100 years since a total of 845 New Zealanders were killed in a matter of hours on October 12, 1917.
Another 1900 were wounded near a Belgian village called Passchendaele during World War I while trying to capture German positions.
Europe Correspondent Tova O'Brien is in Passchendaele for the centenary commemorations, and there are commemorations across the country.
Live updates have now ended.
4.30pm - Governor General Dame Patsy Reddy says the new memorial "proffers a message of hope, peace and tolerance".
4.05pm - The new memorial has just been unveiled at Pukeahu National War Memorial Park. Designed by Belgian artists Niko Van Stichel and Lut Vandebos, it combines the symbolism of the laurel wreath, traditionally used as a symbol of victory, and the memorial wreath, traditionally used to pay tribute to those who have died in battle. The underlying message is that there are no winners in war.
