Mid-Canterbury (New Zealand electorate)

It existed from 1928 to 1946 and was represented by six Members of Parliament, including Mary Grigg, the first woman National Party MP.

[2] David Jones was the first representative, winning the 1928 election by a wafer-thin majority of 55 votes (0.59%) against Jeremiah Connolly;[3] he had previously held Kaiapoi and Ellesmere.

Connolly died on 2 October 1935 and as this was only weeks prior to the 1935 election, the seat remained vacant and no by-election was called.

[6] At the next election in 1938, Herring was narrowly beaten by Arthur Grigg of the National Party.

[7] Grigg enlisted in the NZEF as a Major in World War II, and was killed in action in Libya on 29 November 1941.
