Luxton became prominent in the Waikato branch of Federated Farmers, serving as a Dominion councillor before his election to Parliament. He continued a family involvement with the Tatua Dairy Company as a director for several years. He entered Parliament as the result of the 1966 New Zealand general election as the National Party member for Piako and then, after boundary changes for the 1978 election, Matamata. He represented the predominantly rural electorate for 21 years to 1987. He was elected Chairman of Committees in 1976, a position he held until National's defeat in 1984. Interested in Pacific Island affairs, he led a government-sponsored tour of eight Pacific nations in 1976 to investigate the potential of increasing New Zealand involvement in local industries there.
On Luxton's retirement from politics in 1987, his son John Luxton succeeded him in the Matamata (later Karapiro) electorate, from 1987 to 1999.
After politics, Luxton was actively involved in his family's horticulture block at Katikati. He died in Morrinsville on 29 August 2005, at the age of 82. His wife, Margaret Luxton, died the following year.
In 1977, Luxton received the Queen Elizabeth II Silver Jubilee Medal. In the 1987 Queen's Birthday Honours, he was appointed a Companion of the Queen's Service Order for public services. In 1990, he was awarded the New Zealand 1990 Commemoration Medal.
