Hi Lu,
No date given, but probably late 1920's, early 1930's. Yes, that is my grandmother, Margaret Hart standing in the doorway. identity of other woman unknown. Thought it might have been a family member too, but not recognisable.
I do know the family moved down to Milton, near Dunedin around 1930 period. But they didn't stay there that long, and returned to Christchurch.
