The provinces of the Colony of New Zealand existed as a form of sub-national government. Initially established in 1846 when New Zealand was a Crown colony without responsible government, two provinces (New Ulster and New Munster) were established. Each province had its own legislative council and Governor. With the passing of the New Zealand Constitution Act 1852 the provinces were recreated around the six planned settlements or "colonies". By 1873 the number of provinces had increased to nine, but they had become less isolated from each other and demands for centralised government arose. In 1875 the New Zealand Parliament decided to abolish the provincial governments, and they came to an end in November 1876. They were superseded by counties, which were later replaced by territorial authorities.
