William Nosworthy

William Nosworthy (1867-1946) was a New Zealand politician. He briefly served as Minister of Finance and then Minister of External Affairs in the Reform Party government.

Nosworthy entered Parliament as the member of parliament for Ashburton in the 1908 election. He held this seat until his retirement at the 1928 election, serving through seven terms of Parliament.

He was first appointed to Cabinet in 1919, being appointed Minister of Agriculture and Minister of Immigration by William Massey. When Massey died in 1925, Nosworthy gained the more important role of Minister of Finance in the interim government of Francis Bell.

Nosworthy contested the leadership race to succeed Massey, but was defeated by Gordon Coates. He continued to serve as Minister of Finance until the following year, when he was given the External Affairs portfolio instead. He held this position until his retirement from politics.
