Geoids represent a hypothetical global sea level as it would be shaped by gravity if oceans could flow unobstructed though land. New Zealand’s official geoid, New Zealand Quasigeoid 2016 (NZGeoid2016), is commonly used in New Zealand, and its predecessor, New Zealand Quasigeoid 2009 (NZGeoid2009), was used before this. Several other geoids and global gravity models are also commonly referenced in New Zealand.

The reference surface for New Zealand Vertical Datum 2009 (NZVD2009) was New Zealand Quasigeoid 2009 (NZGeoid2009). NZGeoid2009 has been superseded by New Zealand Quasigeoid Geoid2016 (NZGeoid2016) and New Zealand Vertical Datum 2016 (NZVD20016) in July 2016.

Projections are selected so that they best represent an area on a flat surface. There are separate transverse Mercator projections for each of the following offshore islands: Antipodes, Auckland, Bounty, Campbell Island / Motu Ihupuku, Chatham, Kermadec, Raoul and Snares Islands / Tini Heke Islands.

The Chatham Islands Transverse Mercator 1979 (CITM1979) used to be the projection for Topographic 1:50,000 and other small-scale mapping in the Chatham Islands. Chatham Islands Transverse Mercator 2000 (CITM2000) is now the official projection used in the Chatham

Until May 2010, geodetic coordinates were categorised using orders based on coordinate observation and survey significance. This framework was replaced in 2010 by the Standard for the Geospatial Accuracy Framework (LINZS25005) and Standard for Tiers, Classes and Orders of LINZ Data (LINZS25006).

The Rules for Cadastral Survey 2010 that came into effect on 24 May 2010 have different accuracy requirements to their predecessor Surveyor-General’s Rules for Cadastral Survey 2002/2.

A geodetic datum defines a reference framework for specifying locations on the Earth's surface. Two geodetic datums are currently used in New Zealand, and others have been used in the past.

District and city councils are responsible for allocating road names and property numbers.

Some preliminary requisition analysis has been undertaken for the Cadastral Survey Rules 2021 (CSR 2021). The following trends have been identified.

New Zealand has sovereign rights over a vast area of ocean, along with the fishery, mineral and petroleum resources that may exist in that area.

In some circumstances, a licensed cadastral surveyor may need authorisation from the Surveyor-General to enter land to conduct a cadastral survey or install a survey mark. This page outlines information about applying for this authority.
