In New Zealand, the terms "valuation" and "valuer" usually relates to one who undertakes that professional role in terms of the Valuer Act 1948 requirements or the unregulated or voluntarily self-regulated (if members of PINZ) plant and machinery, marine or art valuers. Whereas, the term "appraisal" is usually related to an estimate by a real estate sales person or licensed agent under the Real Estate Agents Act 2008. The Real Estate Institute of New Zealand includes many valuer members, but the governing legislation for sales and agency (disposal of interests of land on behalf of others) does not extend to include provision for that role by valuers regardless of membership of NZIV, RICS or PINZ.
