Registered valuers must follow integrity, independence, confidentiality and disclosure rules in the model code of conduct. Model code requires registered valuers to observe integrity and fairness, maintain professional competence and due care, and preserve independence by avoiding conflicts of interest, disclosing relevant associations, refraining from trading in subject securities once associated, and not charging success fees; it also requires confidentiality, contemporaneous records retention, cooperation with inspections and regulators, transparent contractually disclosed remuneration, prohibition of gifts that impair independence, and restrictions on over-commitment or discreditable conduct.
