Iain, the Wellington Militaria Collectors Club had its Christmas luncheon just this Sunday at fellow forum member Wayne Ihaka's house.
Interestingly, Wayne brought out a folder of A4 size photos of various NZ badge collections, which just happened to include a photo of your own collection.
Have you sourced a set of 5th Wellington badges yet? or are you going to play the "my collection is 1911 to 1953" card?
