What motivated his great-uncle Private William Harold, No 22662, to join the war effort as a member of the 16th Reinforcements to the New Zealand Machine Gun Corps isn't clear, Mr Harold said.
"Why would a man with a wife and three little children leave his Dannevirke farm and go to war? At the time families here would have had a clearer understanding of the horrendous impact of World War I, with stories of Gallipoli.
"Whatever prompted my great-uncle William, 27, to join the front line of the battle, we don't know, but we do know like so many others, he is listed as having no known grave.
"My great-aunt Bertha was left a widow and had to just get on with it, through the war years, the Depression and then World War II.
"I was lucky to meet her eldest son Ernie when he was in his 90s. He told me hadn't wanted to enlist for WWII, but did so, although he'd said, 'bugger it, I'm not going to war, my mother had too much crap from wars'. But, along with his youngest brother Hugh, he enlisted in 1944 and they both served overseas."
Mr Harold hopes his thought-provoking artwork gets people thinking about the stories of others left behind. Visitors can view Te Manawaroa at the Dannevirke Art Society's rooms in McPhee St, on Thursday and Mr Harold hopes to have it on public display for Anzac Day next year.
