The gadfly petrels are a widespread group of small pelagic birds in the Pterodroma genus. Gadfly petrels that have been observed caught in New Zealand trawl and longline fisheries include grey-faced petrel (Pterodroma macroptera gouldi) and white-headed petrel (Pterodroma lessonii).
Between 2002–03 and 2020–21, there was no observed fishing in mackerel purse seine fisheries in the East Coast North Island area.
