The National Libraries Paperspast website has revealed many details of my families which would have been very difficult to unearth.
This month they will be adding or have added:
Poverty Bay Herald (gap: 1902)
Lyttelton Times (1851-1862)
Evening Post (July-December 1871, 1916-1945)
Thames Star (1901-1920)
Albertland Gazette (1862-1864)
The Colonist (1857-1889)
Otago Daily Times (1861-1900)
Waiapu Church Gazette (1921-1945)
So be sure to revisit.
