Thank you to Adele Geradts for her research and compiling this information.

Staff at Te Hāpua: Halswell Centre, Upper Riccarton, and Spreydon libraries researched the war stories of men who enlisted from the Halswell area. Ready either to live or die valiantly; are the words enscribed on the Halswell War memorial. These are the stories not only of the men who died during the war, but those that came home to live, their stories just as valient as the men who never made it home.

Their names were gathered from the Halswell War Memorial, the Roll of Honour Board at the Halswell Hall, and newspaper articles from the time.
