Mongonui was a parliamentary electorate in the Far North District in the Northland region of New Zealand, from 1861 to 1870.
In the 1860 electoral redistribution, the House of Representatives increased the number of representatives by 12, reflecting the immense population growth since the original electorates were established in 1853.
[1] The electorate was formed through the Representation Act 1860, which describes its area as follows:[2] This electoral district comprises so much of the North Island as lies to the north of a line from the head of False Hokianga Harbour to the summit of Maungataniwha Mountain, and thence to the mouth of the Pupuke River, at the head of Wangaroa Harbour, including the adjacent islands.Population centres that thus fell within the electorate included Kaitaia and Mangonui (which was spelled Mongonui before the 1880s).
[6] He was succeeded by Thomas Ball, who was elected unopposed on 21 March 1866, but resigned in 1870.
[7] Thomas Gillies, who had previously held two Otago electorates, won the resulting 1870 by-election.
