PINZ incorporated much of the membership of the NZIV, the Institute of Plant & Machinery Valuers (IPMV) and the Property & Land Economy Institute of New Zealand (PLEINZ). PINZ now represents the interests of valuers, property and facilities managers, property advisors and plant and machinery valuers. PINZ has developed into one of the largest professional bodies for standards, qualifications and ethics across all facets of the property profession within New Zealand. It works with government, industry and other professional associations, education stakeholders and the media to promote its standards and views.[33]
However, the recent trend of the business tends to be toward the use of a scientific methodology of appraisal which relies on the foundation of quantitative-data,[10] risk, and geographical based approaches.[11][12] Pagourtzi et al. have provided a review on the methods used in the industry by comparison between conventional approaches and advanced ones.[13]

If a home inspection is performed prior to the appraisal and that report is provided to the appraiser, a more useful appraisal can result. This is because the appraiser, who is not an expert home inspector, will be told if there are substantial construction defects or major repairs required. This information can cause the appraiser to arrive at a different, probably lower, opinion of value. This information may be particularly helpful if one or both of the parties requesting the appraisal may end up in possession of the property. This is sometimes the case with property in a divorce settlement or a legal judgment.[16]

A property's appraisal value is influenced by recent sales of similar properties and by current market trends. The home's amenities, the number of bedrooms and bathrooms, floor plan functionality and square footage are also key factors in assessing the home's value. The appraiser must do a complete visual inspection of the interior and exterior and note any conditions that adversely affect the property's value, such as needed repairs.
