CSDs used to record new or existing non-boundary marks or to record new or adopted survey information.
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.
