Hello.
Primary school enrolments may be a way to go for looking at names of potential interest, and if so, earlier published school reunion books may contain enrolment lists. [Local public libraries]. In more recent years the NZ Society of Genealogists, and branches, have published lists for members to research.
However later published versions abide by the current privacy legislation, so do not list the potentially living. Therefore 100 years pre their publishing date.
Have sent a PM.
Alan.
