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.
