Cape Brett is a promontory on the northern North Island coast in New Zealand. Located at the end of the 15 kilometre-long Cape Brett Peninsula, the head extends north into the Pacific Ocean at the eastern end of the Bay of Islands.
A lighthouse stands at the end of the peninsula, which rises to some 360 metres at its northern end. A moted landmark, the natural arch of Piercy Island, lies two kilometres off the cape.
CapeBrett Lighthouse is situated at the entrance to the Bay of Islands and overlooks Piercy Island (Motukokako) better known as the "Hole in the Rock".
CapeBrett was named by Captain Cook in 1769 in honour of a Lord of the Admiralty, Rear-Admiral Sir Piercy Brett.
CapeBrett was also the first in New Zealand to float the rotating light on a bed of mercury.
