Research into the life of the first New Zealand Company colonist to step ashore at Petone on January 22, 1840, made me read a lot of 19th century New Zealand history -- both that written close to the period, and the substantial re-writing done by the Waitangi Tribunal from the late 20th century on.
The First Colonist - Samuel Deighton 1821-1900, which is advertised on this website, draws upon his letters and other primary sources, early settler histories, biographies, more recent histories, and Waitangi Tribunal reports. I expected tribunal reports to deal with history, but I did not expect them to be finely crafted arguments in support of the claims they purport to investigate. Taxpayers should be outraged that a government-funded body is writing a new history in which the Crown is depicted as deceitful, settlers rapacious, and Maori as helpless victims in need of compensation.
