New Ulster 1846–1852, in red
New Ulster was a province of the Colony of New Zealand that existed between 1841 and 1853. It was named after the Irish province of Ulster.
Between 1841 and 1846 the province included all the North Island north of the Patea River. With the passing of the New Zealand Constitution Act 1846, the province came to include all of the North Island. Like the other province of New Zealand at the time, New Munster Province, New Ulster Province was headed by a Lieutenant-Governor who reported to the Governor of New Zealand.
In 1852, a new Constitution Act was passed, and the province was divided into Auckland, Wellington and New Plymouth provinces.
