Clay carvings considered the "Gallipoli Holy Grail" have given an extraordinary new meaning to Anzac Day, for one Rotorua whanau.
In July 1915, 500 fresh reinforcements from Te Ope Tuatahi Maori Contingent landed on the shores of Anzac Cove.
The contingent was delegated hard labour jobs such as digging and building trenches such as the "Big Sap" which connected Anzac Cove near Ari Burnu to No. 2 Outpost.
Conditions were hot and dry, and water was scarce.
For the past century history books have mentioned the Maori carvings at the Big Sap.
Some included photos and drawings.
But the mystery soldier who carved the designs into trench walls was not identified until 2015, when Te Papa staff researched the contingent.
The head of Te Papa's Matauranga Maori collection, Puawai Cairns, approached Weta Workshop to recreate the carvings from the pictures for the "Gallipoli: The scale of our war" exhibition, ahead of the opening in 2015.
The carvings appeared to be in the style of Te Arawa, and Cairns wanted to put a name to them.
About a week before the opening, she came across a big clue in a photo caption in the digitised Australian War Memorial records.
"'Taratnoke [sic] and the man of the arawa [sic] tribe who carved it."
She posted the image on her Facebook page and Sarah Johnston from Nga Taonga Sound and Vision contacted Cairns to say the carvings were mentioned in the introduction of an archived interview.
"Here is Tuoro Akapita Pango, M.B.E., the spokesman of the Arawa tribe and himself an artist of distinction. When he was on Gallipoli he carved a figure on the side of a trench..."
Pango was not listed in the army service records, but Private Mekiora Akapita 16/128 from Rotorua was the most likely link to Te Arawa.
Te Papa's iwi relationships team made contact with Kingi Biddle, a great-grandson of Private Akapita, who confirmed his koro went by multiple names including Tuoro Akapita Pango.
Biddle and his sister Lauren James never knew about the carvings but they identified their koro in the Australians' photo.
"In other pictures we have seen, he looked quite frail, but seeing him as a young strapping man, that was a real eye-opener for us," James told the Rotorua Daily Post.
Biddle still lives in his great-grandfather's former house in Koutu.
"My first thought was 'Gee my koro's handsome! What happened with some of us?'"
Akapita died in the early 1960s before Biddle and James' father was a teenager, and they knew very little about his time at war, so Te Papa's discovery was huge, James said.
"There was a whole new sense of pride that he still undertook traditional practices there. He did what he knew best with the carvings."
Biddle said carving would have been "second nature" to his koro who was of Ngati Tarawhai and Ngati Whakaue descent.
Carving was in Akapita's bloodlines on both sides, especially his mother's.
Akapita was considered too old to fight in WWII, but he spoke of his hopes for peaceful korero.
"He said 'let's go talk to Hitler and have a gentlemen's conversation'. That reflects the attitude of our people at that time, they took people for their word.
"Koro, his cousins, and his friends, they lost and took lives in a bid to create a world where this would never have to happen again. The best way to honour those men is to be good to each other and act with kindness."
