Learn how to identify the New Zealand sea lion, behave safely around them and report your sighting.

How to identify a New Zealand sea lion

If you need help identifying species, download the Marine mammal sighting form (PDF, 416K or Word, 4,300K). Use the images and descriptions to find out whether or not you're looking at a New Zealand sea lion.

New Zealand fur seals can be distinguished from sea lions by their pointy nose and smaller size. In New Zealand, fur seals also tend to be found on rocky shorelines, whereas sea lions prefer sandy beaches.

If you see a sea lion

If you are in New Zealand and spot a sea lion, you're seeing one of the rarest sea lions in the world. They're Nationally Critical and protected. It's an offence under the Marine Mammals Protection Act 1978 to disturb, harass, harm, injure or kill a New Zealand sea lion. A dog owner whose dog attacks a seal could face prosecution. 

How to behave

  • Minimise disturbance. Stay at least 10 m from them, 20 m if you're with your dog (always on lead).
  • Sea lions are confident with humans. Don't run away from them. Back off slowly if you're too close, and avoid direct eye contact. They are unlikely to pursue you.
  • Unlike fur seals, you can walk between a sea lion and the water, unless they're heading to the sea.
  • Keep an eye out, as a female's fur colour is similar to sand. They might be hidden between dunes.
  • Move slowly away if you're in the water
