David Jones was a Reform Party Member of Parliament in the Canterbury region of New Zealand. In September 1931, he was appointed Minister of Agriculture and Minister of Mines in the United–Reform Coalition Government, but he was unexpectedly defeated in the December 1931 general election. He was a farmer and involved with many farming organisations, and was instrumental in forming the New Zealand Farmers Union, which eventually developed into Federated Farmers. Outside parliament, he was best known for his involvement with the New Zealand Meat Producers Board, of which he was the inaugural chairman, and which he chaired for more than a decade.

The Minister of Agriculture is a minister in the New Zealand Government. It was re-created as a standalone portfolio in 2017 after previously existing continuously from 1889 to 1998, and again from 1999 to 2012. The current Minister is Todd McClay.
