The Bay of Islands is an area on the east coast of the Far North District of the North Island of New Zealand. It is one of the most popular fishing, sailing and tourist destinations in the country, and has been renowned internationally for its big-game fishing since American author Zane Grey publicised it in the 1930s. It is 60 km north-west of the city of Whangarei. Cape Reinga, at the northern tip of the country, is about 210 km by road further to the north-west.
The bay itself is an irregularly-shaped 16 km-wide, 260 km2drowned valley system and a natural harbour. It contains 144 islands, of which the largest is Urupukapuka, and numerous peninsulas and inlets. The three largest inlets are Waikare Inlet in the south, and Kerikeri and Te Puna (Mangonui) inlets in the north-west. The Purerua Peninsula, north of Te Puna Inlet, separates the north-western part of the bay from the Pacific Ocean, and Cape Brett Peninsula extends 10 km into the ocean at the eastern end of the bay. The biggest town is Kerikeri, followed by Paihia. The small town of Russell is located at the end of a short peninsula that extends into the bay from the southeast.
About 700 years ago, the Mataatua, one of the large Māori migration canoes which journeyed to New Zealand from Hawaiki, was sailed to the Bay of Islands (from the Bay of Plenty) by Puhi, a progenitor of the Ngāpuhi iwi (tribe) which today is the largest in the country. Māori settled and multiplied throughout the bay and on several of its many islands to establish various tribes such as the Ngāti Miru at Kerikeri. Many notable Māori were born in the Bay of Islands, including Hone Heke who several times cut down the flagpole at Kororāreka (Russell) to start the Flagstaff War.
