Federal law requires appraisers to have a state license or certification when working on federally related transactions, such as appraisals for loans made by federally insured banks and financial institutions. The Appraisal Foundation (TAF) offers information on appraisal licensing. There is no such federal requirement for assessors, although some states require certification. For state-specific requirements, applicants should contact their state board.
There is a key distinction between the role of a real estate agent and a valuer, as an agent may advocate for its principal's interests, whereas a valuer must impartially and independently provide opinion as to value. Lawyers, Conveyancers and Real Estate Agents are permitted to act in the sale of real estate under quite different legislation from that which governs valuers. The provision for the role in relation to Lawyers and Conveyancers is the Lawyers and Conveyancers 2006.
There are also voluntary professional bodies for real estate valuation such as the Royal Institute of Chartered Surveyors ('RICS') and the Property Institute of New Zealand ('PINZ'). Both of these bodies have a wider membership, beyond real estate valuers. PINZ has over 2,500 members in New Zealand and overseas (such as ex-pats in the UK, Asia and Australia). PINZ has a service level agreement with the NZIV, whereby PINZ contracts to perform tasks for the statutory professional body, NZIV. PINZ was formed in 2000 to act as the voice of the property professions. There have been 'political divisions' within the valuation profession in New Zealand, expressed at AGMs and through 'proxy wars' over the last 20 years or so. Many valuers are supportive of amalgamation of the NZIV functions under the multi-disciplinary voluntary body PINZ, whilst many others wish to retain a separate statutory professional body for valuers (the NZIV). There are various reasons in the debate and the governing legislation is under review and amendments or repeal is being considered. At present, the Act remains in force and the NZIV is legally a distinct body with statutory functions, powers and duties.
