Applications for resource consent for listed heritage items should take account of the conservation principles of the ICOMOS New Zealand Charter for the Conservation of Places of Cultural Heritage Value (ICOMOS New Zealand Charter 2010).

The International Council on Monuments and Sites (ICOMOS), is a non-governmental organisation of heritage professionals engaged in the conservation of places of cultural heritage value and dedicated to the conservation of the world's historic monuments and sites.

The ICOMOS New Zealand Charter 2010 is a set of guidelines on cultural heritage conservation. The Charter is widely used in the New Zealand heritage sector and is a recognised benchmark for conservation standards and practice. It is used by central government ministries and departments, by local bodies in district plans and heritage management, and by practitioners as guiding principles. The Christchurch City Council has adopted the charter as part of its conservation policy.
