The pattern of Maori land alienation depicted in the time sequence maps has been derived from a computerised mapping database especially developed for this project. This database was developed using the research into the block histories which are contained in Volume
8 Parts 1–4. In addition other published sources provided supplementary information on old land claims and land affected by confiscation. The Ministry of Maori Affairs provided data on the existing Maori customary and freehold land in 1997.
The mapping database enables a wide range of information to be depicted for any period and modern information can be shown as layers on top of the historical base. Accompanying the research reports are large multi-coloured wall charts showing the alienation of Maori land from 1840. All the small land block maps used in Volume 8 Parts 1–4 are derived from this mapping database.
5 Data used for 1939is sourced from the 1940Historical Atlas project (now held in the Alexander Turnbull Library map collection).
6 Data supplied by the Ministry of Maori Development in 1997 enabled existing Maori customary and freehold land to be identified independently of the research and land block analysis carried out under the Hauraki Treaty Claims research project.
