CSDs used to depict a subdivision of land that is completed in stages by the successive deposit of a Proposed Unit Development (PUD) plan and a First Stage Unit Plan together, and one or more further Stage Unit Plans (if any), and a complete unit plan (called Complete Stage Unit Plan in Landonline).
This list of approved cadastral survey datasets (CSDs) are examples of plans approved under the Cadastral Survey Rules 2021 in terms of the category listed, but they are not necessarily examples of best practice.
More examples may be added over time. Please provide feedback to customersupport@linz.govt.nz
If you cannot find an LT number in Landonline it may have deposited, so try searching for it as a DP number.
