The Mackintoshs moved to New Zealand in 1866, where he was also a runholder.[5] He first bought the Strathmore estate in the Otautau district, and later the Gladfield estate.[2] He retired from farming in 1884 and moved to Invercargill.[2]
From 1880 until shortly before his death, Mackintosh was a member of the Southland Education Board. He set up the Aparima road board.[6] While obituaries in The Evening Post (Wellington) and The Star (Christchurch) mention his membership of the Southland Provincial Council,[3][6] his name does not appear on the council's roll compiled by Guy Scholefield in his 1950 edition of the New Zealand Parliamentary Record, 1840–1949.[7] For a time, he was chairman of the Wallace County Council.[3]
He was an advocate of cheap government loans for settlers.[5] In the 1896 election, the Wallace electorate was contested by five candidates, and Mackintosh came last.[10]
