The BESTPRACTICE standards have been modelled on equivalent overseas standards and adapted to the New Zealand situation. BESTPRACTICE Clinic Standards itemises the standards of service, facilities, equipment, and management considered essential in veterinary practice. The standards encourage the ongoing critical evaluation of the practice's surgical, medical, diagnostic and nursing protocols in order to maintain a high level of excellence. Practices are audited by independent veterinary auditors prior to initial accreditation and then every two years. The current auditors are the Ministry of Agriculture and Forestry Verification Agency.
