Duncan McFadyen Rae CMG (2 June 1888 – 3 February 1964) was a New Zealand politician of the National Party.
[1] He taught at East Cape School in Invercargill for ten years, and was then Vice-Principal (1924–1929) then Principal (1929–1947) at the Auckland Teachers' Training College.
[2] He represented the Auckland electorates of Parnell from 1946 to 1954, and then Eden from 1954 (succeeding Wilfred Fortune) to 1960, when he retired.
[3] Rae suggested that an organisation for the protection of the country's heritage should be set up and put in a private member's bill in 1953.
Whilst this did not proceed, the First National Government of New Zealand (of which he was a member) took responsibility of the issue and the Historic Places Act 1954 was passed, which established the National Historic Places Trust as a non-governmental organisation (NGO).
