Rhys Smith NZ Methods of Measurement

Realserve was tasked with helping the Auckland District Law Society (ADLS) better understand the value of having survey accurate measurements to determine the rental area of a leased space.

We explained how measurement guidelines can affect areas, the difference between the four methods of measurement, and highlighted areas to be included and excluded, in accordance with the NZ Property Council guidelines.

Watch the video below to hear our New Zealand manager, Rhys Smith, explain dealing with NZ Commercial Leases from a surveying point of view. Don't hesitate to contact us to find out more on this subject and how we can help you.
