This is the largest discipline of surveying in New Zealand. The cadastre is the means of defining the dimensions and location of land parcels described in legal documentation.  

New Zealand operates a digital titles register and digital cadastre called Landonline.  The government guarantees the ownership of land based on accurate surveys recording  the location of the parcel of land and the boundary dimensions.

 

When a new development or subdivision changes property boundaries, a land title survey is required and a new survey plan is prepared and electronically submitted to Landonline. The surveyor must first search survey plans in the area then locate old boundary or reference marks and prove their reliability before accurately defining the new or existing boundaries. 

 

Only Licensed Cadastral Surveyors are authorised to conduct land title surveys in New Zealand, although trained technicians often perform such work under direction.
