Frank Langstone (10 December 1881 – 15 June 1969) was a New Zealand Member of Parliament, Cabinet Minister and High Commissioner to Canada .

His older sister Katherine took care of the family, thus financial pressures prevented him having a proper education, though he was an extensive reader.

He briefly lived in Auckland before returning to Te Kūiti in 1918 to become the proprietor of a railway restaurant in Taumarunui, and a fish-and-chip shop in 1919.

[2] Langstone first contested the Waimarino electorate in the 1919 election, but was beaten by the incumbent, Robert William Smith of the Liberal Party.

Throughout his parliamentary career Langstone consistently advocated for the creation of a state-owned bank, development of lands for agriculture, a financial safety net for farmers.

Despite this, his pursuit of ideas and views (particularly on financial matters) which were not shared by his more senior colleagues prevented him being appointed to more influential roles.

He impressed senior civil servants with his administrative abilities and had particular concerns regarding soil erosion, river control and afforestation.

[4] He returned after only six months later, he resigned from cabinet and publicly alleged that Fraser had double-crossed him after promising him the position of Minister to the United States which was given to Walter Nash instead.

During the 1951 New Zealand waterfront dispute he published a pamphlet opposing the heavy-handed emergency regulations imposed by the First National Government.
