The exhibition Not A Week Goes By was created by the South Otago Museum and the In Memoriam Association, based in New Caledonia.
It depicts the impact of World War 1 on New Zealand and New Caledonia.
The exhibit focuses on monuments in Balclutha and Noumea.
Mr Ross researched the lives of five Balclutha men and their families depicted on the South Otago town's war memorial.
``The families of the soldiers have said it was of a high standard,'' Mr Ross said.
The display was later expanded to include information about Maori soldiers.
The experiences of and impact on the South Otago men, Maori and Pakeha, are compared with the experience of New Caledonians, including French settlers and Kanaks.
The display has interactive touch-screen components, timelines, text and photographs.
The exhibit began a tour of New Zealand last year but was recently packed up and set up in Noumea, New Caledonia.
It will be opened on November 10 and remain there until December.
South Otago Museum curator Gary Ross, who helped research and create the display, said this was ``phase three'' of the exhibit.
In its first incarnation, the exhibit had already been displayed in New Caledonia, Balclutha and Dunedin.
It then went through an ``evolution'' for phase two, which was displayed in Waiouru, Taupo, Malborough, Akaroa, Hokitika and Timaru before returning to Dunedin.
Mr Ross leaves for New Caledonia tomorrow, where he will help open the exhibit.
He said the team that created the display ``will be back together again'' for its second international opening.
The display was one of three finalists in the New Zealand Museum Awards for best exhibition for a regional museum in the social history category earlier in the year.
He said it was ``a big breakthrough for South Otago''.
