CSDs used to depict a subdivision of land into units and common property (if any) in a single stage that is not a layered unit title development.
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.
