Three species of beaked whales, Mesoplodon peruvianus, M. ginkgodens and M.
densirostris, are newly recorded from New Zealand on the basis of stranded
specimens, M. peruvianus was previously known from the eastern tropical Pa
cific; M. ginkgodens from the sub-tropical and tropical waters of the wider
Pacific and equatorial Indian Oceans, and M. densirostris from Australian
and other warm temperate to tropical waters. Diagnostic skull characters fo
r the three species are discussed and illustrated. Previous records of M. g
inkgodens from the Chatham Islands, and M. densirostris from the east coast
of New Zealand and Macquarie Island, are incorrect.
