Waitangi is a locality on the north side of the Waitangi River in the Bay of Islands, 60 kilometres north of Whangarei, on the North Island of New Zealand. It is close to the town of Paihia, to which it is connected by a bridge near the mouth of the Waitangi River estuary. While Statistics New Zealand and NZ Post consider the southern boundary of Waitangi to be the river and estuary, with the area further south being part of Paihia, the area by Te Tī Bay, immediately south of the river, is sometimes referred to as part of Waitangi.

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 (37 mi) north-west of the city of Whangārei. Cape Reinga, at the northern tip of the country, is about 210 km (130 mi) by road further to the north-west.
