Analytics to identify and connect successors to whenua

This Spearhead project is creating smart data analytics tools to help address these challenges and keep track of the growing network of shareholders and their descendants.


  • Missing and incomplete records mean that thousands of Māori who are rightful shareholders in Māori freehold land can’t be tracked down, creating problems for land succession, economic development, and maintenance of whānau relationships.
  • This Spearhead project co-designed with Māori is creating smart data analytics tools to help address these challenges and keep track of the growing network of shareholders and their descendants.
  • The work embodies tikanga, reflecting the culturally embedded nature of this task and attaching information to real people, rather than simply assembling faceless databases of information.
  • The technology will enable iwi, hapū and other Māori organisations to work collaboratively to find missing members while protecting confidential and taonga information.

Helping Māori reclaim their ancestral lands.

The Māori-owned business Parininihi ki Waitotara (PKW) Incorporation has built a thriving operation in Taranaki spanning forestry, crayfish exports, agri-business and commercial property. Over 10,300 owners should receive annual dividend payments from PKW’s business activities, sharing the wealth in the way intended by the original 5,396 owners who incorporated PKW in 1976.

Finding whenua owners

As time goes by, PKW and many other Māori land organisations are facing the same complex problem - tracking down all of the rightful co-owners, so they can benefit from the development and use of their ancestral lands.

Currently, the task is largely manual and requires sifting through multiple sources of online and print data sources. Now a Science for Technological Innovation (SfTI) National Science Challenge Spearhead project sees University of Auckland, Victoria University of Wellington and Parininihi ki Waitotara partnering to tackle the problem with new data science and research that embodies Vision Mātauranga and kaupapa Māori.

Identifying rightful owners - how does it work?

The project draws on data discovery and modelling technologies and methodologies to create a more complete and accurate picture of land ownership and succession, which can be quickly accessed and visualised.

Smart algorithms that match names from multiple sources have been created, “fuzzy” word matching and transcription error probabilities have been applied to data to match different name versions associated with the same person. Finding records of deceased landowners involves scanning death notices across multiple publications, including newspapers, and accessing Māori Land Court records.

Automating that process has involved the team developing its own Optical Character Recognition (OCR) algorithms, as standard OCR software applications were unable to decipher old records due to poor print reproduction quality.
