Surveyors use field books to record measurements made 'on the job'. Field books show the bearings and distances between each survey mark involved in a survey.
Field books can date back more than 160 years. Older books may show place names and physical features (eg pa sites, hills, houses, etc). They are typically bound volumes.
LINZ holds all field books, as part of the cadastral survey database. The originals of 800 of the earliest field books have been digitised and are now held by Archives New Zealand.
You can order copies of particular pages from a field book. You will need the field book reference (found on survey plans, and in old plan and field registers) and the page numbers. In some cases, knowing the surveyor's name can help you find the field book reference.
