The Allan Herbarium contains species from around the world but specialises in indigenous and exotic plants of the New Zealand region and the South Pacific. There are over 620 000 specimens in the Allan Herbarium with 5000-8000 being added annually. Two-thirds of the specimens are of indigenous plants with the remainder divided between naturalised, cultivated, and foreign specimens. It also has specialist collections of seed, fruit, wood, plant leaf cuticle, liquid–preserved specimens, and microscope slides. The oldest samples are the 91 duplicate specimens collected by Joseph Banks and Daniel Solander during Captain James Cook´s first voyage to New Zealand, 1769–1770.
