Hi 1921 census has her as Annie Eliza wood,ni daughter of the hickmans with them on the 1921 census,so maybe passed on or living in a school somewhere outside of Camberwell,in 1911 Annie Eliza had been a companion live in to a older woman in st Peter's port,more like a nurse aid then servant per day,looking after the older woman's physical health etc,she seems to have remained a spinister,hard to say if Annie Eliza came to nz to visit her four brothers or move here,but she was in regular contact with her brother John ,my x2 great grandfather by letters etc so anything is possible
