Miles John Anderson (born 1968 or 1969) is a New Zealand farmer and politician. He was elected as a Member of the New Zealand House of Representatives for Waitaki, representing the National Party, in the 2023 New Zealand general election. From a farming background, he was with Federated Farmers, chaired one of their national bodies, and was on their national board.

Anderson was born in 1968 or 1969,^[1] and grew up in Southburn, a locality in the Waimate district.^[2] His family had farmed in the area for generations.^[2] He was educated at Southburn School, followed by St Kevin's College in Oamaru as a boarder.^[3] He went on to study at Massey University, from where he graduated with a Bachelor of Agriculture degree in 1992.^[2][4]

After university, Anderson joined other farmers in 1992 to set up a livestock ultrasound scanning service. Initially servicing the central South Island, the company expanded into South Australia.^[3] Anderson was involved in that company for 20 years.^[2] He took over a 220-hectare (540-acre) farm from his father in 2004; he mainly runs sheep.^[3]

Anderson was the chair of Federated Farmers' South Canterbury Meat and Fibre in 2016.^[5] He was then the national chair of the group from 2017 to 2020, and had it renamed to Meat & Wool so that wool would get more prominence.^[3][6] He was spokesperson for Federated Farmers on rural security.^[7] In this role, he supported the Sixth Labour Government's gun reform following the Christchurch mosque shootings that resulted in the Arms (Prohibited Firearms, Magazines, and Parts) Amendment Act 2019,^[8] but criticised the lack of an exemption for semi-automatic rifles for pest control.^[9]

Upon his election to parliament, Anderson leased out his farm.^[10]

Anderson was selected by the National Party to contest the safe electorate of Waitaki at the 2023 election, succeeding Jacqui Dean who had held the seat since the 2008 election.^[11] He was 59th on the 2023 party list.^[12]

The election night results showed Anderson had been elected with a 10,359-vote majority over Labour's Ethan Reille.^[6] Following the release of the final results on 3 November 2023, Anderson's margin increased to 12,151.^[13]
