We accredit private sector providers to carry out certain types of work to help us acquire, manage and dispose of property.

Like other Crown agencies, we use accredited suppliers to acquire and dispose of property under certain pieces of legislation, primarily the Public Works Act 1981. Accreditation ensures our suppliers have the expertise and experience to carry out this work to a high standard.

Accreditation process

To become accredited suppliers, applicants need to prove they have the technical competence to carry out the work, and have robust quality control and administrative systems. 

For more information on the accreditation process and what needs to be addressed in applications, please see the attachments at the bottom of this page – Procedures for Becoming a Crown Property Accredited Supplier and Conditions of Crown Property Accreditation.

ELFI Database for accredited suppliers

We hold historic Crown property paper files from our predecessor organisations, including the Department of Survey and Land Information, the Department of Lands and Survey, and the Ministry of Works. Accredited suppliers often need to consult these files when acquiring or disposing of land for Crown agencies. 

This historic information can be accessed through the ELFI database (below), which is available to accredited suppliers and to other researchers approved by LINZ.
