John I think I have cracked the badge mystery.
When I put all my WW1 Pipe Band photos in a date order I'm starting to see a clear evolution of wartime NZ Scottish uniforms.
The 1914 NZEF Pipe Band, the Auckland Pipe Band and the 1919 "New Zealand" Pipe Band are all using the instruments and equipment that was donated by the three Scottish societies of Dunedin.
The following photo was taken in 1918 by Thomas Frederick Scales, it shows a pipe band standing at attention outside the YMCA building in the New Zealand training camp at Sling.
The exceptionally tall Pipe Major is undoubtedly the same Pipe Major from the 1919 photos.
The 1919 New Zealand Pipe Band is undoubtedly the 14th South Otago Regiment Pipe Band, and the hat badge being worn by them is that of the 14th South Otago Regiment.
