Houhora is a locality and harbour on the east side of the Aupouri Peninsula of Northland, New Zealand. It is 41 km (25 mi) north of Kaitaia. Waihopo, Te Raupo, Pukenui, Raio and Houhora Heads are associated localities on the southern shores of the harbour. State Highway 1 passes through all these localities except for Houhora Heads. Te Kao is 24 km north west, and Waiharara is 22 km south east.
The harbour is long and narrow, mostly sheltered but with exposed sand banks at low tide. There is a deep channel along the southern shore as far as Pukenui Wharf. Mt Camel (also called Mt Houhora) is a 236 metre hill forming the North Head. The South Head is a flat area. The population was 837 in the 2006 Census, a decrease of 78 from 2001.
Houhora Mountain was the first part of New Zealand that the early explorer Kupe saw, but he thought it was a whale, according to Māori legend. Houhora was a Māori base settlement in the early 14th century. Snapper, seals, dolphins, moa and other birds were food sources.
