Often overlooked is the value of school records.
Sure they give you details on the child, but the extra info is invaluable for building a picture of our ancestors,
Look at GUARDIAN, ADDRESS, past and future SCHOOLS & DESTINATIONS
Plus you can often get birthdate (although it can vary)
The Hauraki indexing group indexed many of the schools and the info is available on the NZSG Index Cd's
Thames Library has photocopies of these registers in the closed archive section, behind the front desk
The Treasury has some copies, more to come
Archives Auckland do have alot of school records that can be viewed. Search at Archway.
One exception - Sadly no early Catholic School records pre 1900 are available at archives or at catholic archives
School Reunion books are also excellent for learning more about the school plus Newspapers for reports on school reunions. For instance in the 1950s several schools (Tararu or Shellbank, Waiokaraka and Thames High) had reunions and reports in the papers listed names of those attending and several old entrants names.
These are filed in the SCHOOLS FOLDER at The Treasury, Thames.
