Moerewa is a small town in the Northland Region of the North Island of New Zealand. It is unusual for its high proportion of Māori - over 80% of the population. It is located close to the Bay of Islands five kilometres to the west of Kawakawa.
The population was 1533 in the 2006 Census, a decrease of 129 from 2001.
A service town for the surrounding farming industry, its main industry is the freezing works. During the economic slump of the 1980s, many of the town's industries were badly affected, and unemployment soared. For this reason, the town's population has dwindled in recent years, although there are signs of an economic revival in the district.
Moerewa is on State Highway 1.
Moerewa was formerly served by the Opua Branch of the North Auckland Line railway. The line was originally built to link the Bay of Islands with Whangarei, and the complete route opened on 13 April 1911. From December 1925 until November 1956, the Northland Express train ran through Moerewa, providing a direct service to Auckland. After it ceased to run, passengers were served by mixed trains between Opua and Whangarei until 18 July 1976. In 1985, freight services ceased and the line from Moerewa to Kawakawa was dismantled. The line from Otiria, the present northern terminus, to Moerewa remains in place but is disused.
