Mr Farley said he thinks there will be increased interest in buying toy soldiers due to the 100th commemoration but the extent of interest was as yet unknown.
"If direct descendants of soldiers who fought in World War I bought just one toy soldier as a commemoration we would have to make thousands," he said.
The Farley brothers have been making toy soldiers for 22 years, exporting to many countries including the United States, Italy, France, Germany and Britain.
"We even make Turkish soldiers and export them to Turkey," Mr Farley said.
Dave Cowe of Imperial Productions, Greytown, said thought had been given to producing figurines commemorating the centenary.
"We already produce a set of New Zealanders at Gallipoli, in France and mounted New Zealand soldiers in Palestine."
Mr Cowe said Imperial Productions specialises in wars of the Napoleonic era and making figurines to suit.
He said they were "very international".
