We are committed to Quality Assurance

The Property Institute of New Zealand is committed to promoting excellence and high standards among property professionals.





The Property Industry Quality Assurance programme (PIQA) is for firms in New Zealand that provide services in the four professional communities which the Institute represents; Real Property Valuation, Plant and Machinery Valuation, Property and Facilities Management, and Property Advisory.


Williams’ Harvey is accredited with Gold Certification compliance under the PIQA quality accreditation scheme for Real Property Valuation.


Accreditation is granted to firms who demonstrate they operate a robust quality management system, undergo onsite audits, and have an evaluation of recently conducted valuation reports, amongst other requirements. Consequently, it signals to you as the clients and stakeholders that the appropriate policies and processes are in place to achieve industry best practices and consistent quality standards.
