- The New Zealand Burial Locator ver.2 CD available from the NZ Society of Genalogists and
- Searching of online cemetery databases maintained by various District Councils in NZ
The New Zealand Burial Locator CD, which I own, is a great resource and must have for anyone doing extensive genealogy research on ancestors in New Zealand.
Public cemeteries in New Zealand are maintained by the District Council for the area they're located in. About 70% of these districts maintain searchable online databases. A list of the various District Councils, and the cemeteries they maintain, along with links to their online database (if available) can be found at the Clan Fraser New Zealand Cemetery page.
