Both cemeteries now have a large granite plaque that carries the phrase "Lest we forget", honouring the service men and women who are buried there.
The Alexandra Clyde Returned and Services Association initiative had been years in the planning, Otago Southland District vice-president Kevin Harding said.
"It all started about four years ago when a member of the local community brought me a set of photos of [a similar] plaque at Cromwell and ... Wanaka.
"I said if they can do it, then we can do it too."
He said it was a long process, from planning the project to waiting for the large piece of granite to arrive from overseas, but it was worth it.
The plaques were put in place over the past few weeks, a project made possible by contractors, he said.
Alexandra Clyde RSA executive Gerry Sutherland said the plaques had added another "string to our bow" as the group works to strengthen its core pillars of welfare and remembrance.
