Paihia is the main tourist town in the Bay of Islands in the Northland Region of the North Island of New Zealand. It is 60 kilometres north of Whangārei, located close to the historic towns of Russell and Kerikeri. Missionary Henry Williams named the mission station Marsden's Vale. Paihia eventually became the accepted name of the settlement.
Nearby to the north is the historic settlement of Waitangi, and the residential and commercial area of Haruru Falls is to the west. The port and township of Opua, and the small settlement of Te Haumi, lie to the south.
