Jones held numerous offices in local government, and was later described as the foremost expert in the country on local government matters.[1]
He was a member of the Heathcote Road Board, including its chairman. In 1880, he was chosen to represent the Heathcote district on the South Waimakariri Board of Conservators, which later became the South Waimakariri River Board. For some time, he chaired the board and retired from it in December 1887, owing to his parliamentary workload. In January 1882, he was chosen as the Heathcote Road Board representative on the Drainage Board, but he resigned from that role in May of that year.[1]
In 1881, he was elected onto the Selwyn County Council as the representative for the Heathcote riding, and remained a councillor until his death. His main contributions were a principal part in organising the Halswell drainage scheme and securing the Cashmere Hills domain as a public reserve. From 1883 until his death, he was the chairman of the board that administered this domain. He was appointed in 1885 by the Selwyn County Council as their representative on the Hospital Board, and on the Charitable Aid Board, the latter of which he chaired in 1886–87. At the time of his death, he was chairman of the Hospital Board.[1]
The death on 17 December 1886 of John Coster, who represented the Heathcote electorate in parliament, caused the February 1887 Heathcote by-election. There were several people interested in standing in the electorate, including the former Heathcote MP Henry Wynn-Williams,[2] but with Jones and the current Mayor of Christchurch, Aaron Ayers considered as the only contenders of having a chance of success,[3] most other candidates withdrew from the contest. On nomination day on 2 February 1887, Jones and Ayers were nominated. A third person, James Arthur Williams, nominated himself, but could not find anybody to second this motion. Thus, the by-election was a two-person contest.[4] On election day, 8 February 1887, the majority opinion was that Ayers would win.[5] There was great interest in the election, as evidenced by the high turnout. Jones had a considerable majority over Ayers, with 527 and 336 votes, respectively. The 191 votes majority was mirrored by Jones having won all four polling stations.[6][7]
At the 26 September 1887 general election, Jones and J. H. Hopkins were nominated. Hopkins was an active supporter of Jones for the by-election some seven months earlier and had proposed him at the 2 February nomination meeting,[4] but had developed policy differences with regards to the economic recession.[8] Jones and Hopkins received 756 and 309 votes, respectively. Hence, the majority for Jones was 447 votes, and he was elected to the 10th Parliament.[9][10]
Jones was a first cousin of Edward Wingfield Humphreys,[1] who represented the Christchurch North electorate in 1889–90.[11]
