The following picture shows Staff Sergeant Stratford John Collett, NZAPD, Service Number 58324, and Staff Sergeant Alfred Herbert Williams, NZAPD, Service Number 22660.
Both embarked on the 4th October 1918 with the 41st Reinforcements, and the photo is taken aboard the troopship.
Unfortunately the badges are not clearly detailed, but am leaning to the collar badges being type 8/290.
