He returned home lucky to have his life after surviving a mustard gas attack in France, which left him with damaged lungs, and contributed to his premature death at the age of 49.
Mr Nash returned home four years older and with the memories of the horrific conditions of war, and married Ellen and had seven children.
Mrs Brownlee said it was a tough life for their family, with her father busy with his successful blacksmith in Broadwood village and a farm with cows to milk.
He was a real fix-it man, and would repair vehicles and machinery in his spare time, as well as building and making alterations to homes.
His death in 1942 meant his wife was left to raise the children, his eldest son Bill was old enough to tend to the farm while their mother looked after the children.
Mrs Palmer heard about her grandfather a lot from her mother Kath, who was Mr Nash's second eldest daughter, and had a close relationship with him.
"My mother idolised her dad, he was a very caring father," she said.
Mrs Palmer's own father served in World War II and she said Anzac Day was a special day in her home.
Anzac Day services are held throughout Northland today starting with dawn services in Kaitaia, Kerikeri, Kaikohe, Russell, Whangarei, Ngunguru, Dargaville and Maungaturoto. Last year's dawn service in Laurie Hall Park, Whangarei, saw a record number of Northlanders pay respect to those who fought for their country.
