Grey-faced petrels are native to New Zealand, but forages widel over the south-west Pacific Ocean and Tasman Sea. Breeding takes place annually from June to January on islands, rock stacks and headlands from the Three Kings Islands to Omata near New Plymouth.

Grey-faced petrels are considered ‘Not threatened’ by the Department of Conservation and ‘Lower risk’ by the International Union for Conservation of Nature. It has been estimated that there are around 250,000 breeding pairs.

The diet of Grey-faced petrel is mainly made up of squid, but also includes some fish and crustaceans.

Grey-faced petrel occasionally scavenges behind fishing boats and has been caught in New Zealand longline and trawl fisheries.
