She had woven 40 crosses and Mr Hornby's Kauri class made up the shortfall, Ms Walker said, for which she was grateful "especially at such short notice".
The Carterton RSA had donated poppies enough to place one of the small paper flowers in the centre of each cross.
Ms Walker said the cemeteries were close to the border of France and Belgium and not too distant from the village of Le Quesnoy, which New Zealand troops had liberated from four years of German occupation, a week before the end of WWI in November,1918.
Wairarapa soldiers had played a part in the capture of the village, Ms Walker said, and numerous lives were saved.
Mr Hornby found that buried in one of the cemeteries was a soldier named James Wylie, who had been the son of Alexander and Julia Wylie, of Masterton. He planned to personalise a tribute for Mr Wylie, he said.
"Today many streets in the village are named after New Zealand, like Place de All Blacks and Rue Nouvelle Zealande, in thanks to their courage and sacrifice," Ms Walker said.
The event also had been retold in a children's picture book titled Le Quesnoy - The Story of the Town New Zealand Saved.
Ms Walker believed it an honour to be delivering tributes to the graves of the 140 New Zealanders who did not return home.
"It will be a privilege to do this for many soldiers, who may never have been visited by anyone since being buried there."
