Historical society member Ann Nielsen said they wanted to find the tablets for the World War I exhibition in Carterton.
"It came up when we were looking for something for the memorials ... I wondered if anyone does have them stored away somewhere in their shed. Someone somewhere must know where they are."
The society did have a list of the names of the fallen A&P Society members but believed the spelling of some names to be incorrect and wished to verify the correct names using the tablets, Mrs Nielsen said.
Keeping track of historical items like the tablets was important.
"Things in the past aren't getting preserved and there are so many things that when people die just get put it in the rubbish bin."
Wairarapa A&P secretary Lynley Hamilton said they were "at a loss" as to the whereabouts of the tablets.
"No-one actually seems to know what happened."
They had put an appeal for information in their newsletter and discussed the issue with several older society members, but still had no leads.
"No-one really knows, but with this 100 year anniversary people suddenly have an appreciation of history and memorials - but no-one can really guess or have any idea."
Anyone with information regarding the whereabouts of the tablets can contact Ann Nielsen on (06) 379 9233 or call the A&P Society on (06) 379 8124.
