Like other storm petrels, the New Zealand white-faced storm petrel is often known among fishermen as the 'Jesus Christ bird' because it appears to walk on water as it hunts for prey - mainly planktonic crustaceans and small fish taken from the surface of the water.

It is a small, lightly built seabird, quite strikingly marked: grey above with darker flight and tail feathers, pale grey rump, white belly and breast, a white face with a dark grey crown and a dark stripe through and just below the eye. The eye is large and dark, the bill, legs and toes are black, but the webs between the toes are yellowish.

Despite their high numbers, white-faced storm petrels are classed as 'at risk' because they are extremely vulnerable to introduced mammalian predators. They breed in dense colonies on predator-free islands (the largest being c. 840,000 in Rangatira/South East Island in the Chathams). A single egg is laid in a burrow or under dense vegetation between October and mid-December. The chick hatches after about 50 days and is fed nightly until it is around 57 days old, when it fledges.

White-faced storm petrels nest on islands in the outer Hauraki Gulf, notably the Mokohinau Islands. They can be seen from the coastal path on Tiritiri Matangi, as they forage in nearby waters, but sharp eyes and strong binoculars or a telescope are needed; because of their small size and cryptic colouring against the surface of the sea, they are not easy to spot.
