The Maori Land Court Records contain a wealth of information pertaining to whakapapa.
The seven Maori Land Court districts are Tai Tokerau, Waikato-Maniapoto, Waiariki, Tairawhiti, Takitimu, Aotea and Te Waipounamu.
Before consulting Maori Land Court records, you will need some basic information on when the land in question came before the Maori Land Court, and in which district the sitting took place.
Maori Land Court Records can be accessed at the Maori Land Courts, Archives NZ, many of the large public libraries and some tertiary institution libraries.
Many of the old records from the 1800's and early 1900's are written in cursive style writing, so the ability to read this kind of writing is important.
