Military history of New Zealand during World War I
The cost of maintaining the division for two and a half years on the Western Front was appalling. Altogether some 13,250 New Zealanders died of wounds or sickness as a direct result of this campaign, including 50 as prisoners of war and more than 700 at home. Another 35,000 were wounded, and 414 prisoners of war were ultimately repatriated. The total casualties therefrom approached 50,000, well over half the number of those who served in France or Belgium.
