The New Zealand Arthropod Collection (NZAC) is the world’s largest taxonomic collection of terrestrial invertebrates from New Zealand. The NZAC policy is presented that defines the vision for the collection of being managed to the highest international standards, connected through a global infrastructure, and providing high quality, authoritative, and trusted information. The policy also provides context and guidelines for collection activities, and twenty-two objectives are outlined that will be completed over the next 5 years.
