Perth (China Wall) Commonwealth War Graves Cemetery was chosen because it is the resting place of both New Zealand Infantry and Lancashire Fusiliers soldiers, the New Zealand Defence Force (NZDF) said today.
There are 19 known New Zealanders buried and four unknown New Zealanders commemorated in the cemetery.
New Zealand will be represented at the burial by New Zealand Ambassador to Belgium His Excellency Gregory Andrews and European-based NZDF officers.
It is not uncommon for the remains of World War I soldiers to be discovered even today.
This is the third New Zealand unknown soldier to be found in the past five years - the other two were buried in Mesen/Messines.
This year, New Zealand commemorates the 100th anniversaries of the Battle of Messines on June 7 and the Battle of Passchendaele on October 12.
It was on the Western Front that New Zealand made its most significant contribution to World War I, and where it suffered the greatest loss of life.
