A project for New Zealanders who were held as prisoners of war overseas during any field of war and those who were held as prisoners of war in New Zealand (eg. Featherston prisoner of war camp was a camp for captured Japanese soldiers during World War II).
A prisoner of war (POW, PoW, PW, P/W, WP, PsW, enemy prisoner of war (EPW) or "missing-captured") is a person, whether combatant or non-combatant, who is held in custody by a belligerent power during or immediately after an armed conflict. Source: https://en.wikipedia.org/wiki/Prisoner_of_war
During the Second World War New Zealanders in large numbers became prisoners of war, or went 'into the bag' as they popularly called it. One in 200 of New Zealand's population of the time were held in captivity - over 8000 people. This compares with around 500 POWs in the First World War.
