From Vagrant to Resident: occurrence, residency and births of leopard seals ( Hydrurga leptonyx ) in New Zealand waters
In contrast to previous reports that leopard seals ( Hydrurga leptonyx ) are rare vagrants to New Zealand, we show that this species is a regular member of the marine fauna of this region. We present a first analysis from the New Zealand Leopard Seal Database – an extensive collation of 2,711 record...

In contrast to previous reports that leopard seals ( Hydrurga leptonyx ) are rare vagrants to New Zealand, we show that this species is a regular member of the marine fauna of this region. We present a first analysis from the New Zealand Leopard Seal Database – an extensive collation of 2,711 records of leopard seals within New Zealand between 1200 and 2018. Of these records, 51.2% ( n = 1,408) were photographic. Leopard seal sightings have increased over time and been reported in all seasons and regions of New Zealand.
