Before 1916, elections for
Christchurch City Council were held annually. Bishop was elected onto the town and later city council eight times: in 1863–1866, 1869, and 1872–1873. On 15 January 1866, in the first meeting of the year of the city council, Bishop was unanimously voted chairman for the coming year. He was the fourth chairman of the city council. Bishop faced one of the most difficult years in Christchurch City Council's history. George Allen was a leader of several protest groups, and one such group, the ''Ratepayers' Mutual Protection Association'', challenged the right of the Christchurch City Council to exist.
Henry Wynn-Williams, a lawyer, was active with the group and took the case to court. Ratepayers started to withhold their rates, and in April 1866 the Council was forced to drastically cut expenditure in order to fend off bankruptcy. Staff were laid off, street cleaning suspended, some streets no longer lit and contracts cancelled. In May 1866, the city drainage scheme was abandoned, a project that had been estimated to cost
NZ£160,000. A shipment of pipes that had just arrived from England was sold off, and Christchurch's reputation as the "most polluted and unhealthy city" in New Zealand was retained for another 20 years as a consequence. Elections for city council members were held on 8 January 1867, and Bishop's term as councillor came to an end. He was asked to be nominated again, but he declined as being too busy, and having served four years. In the first meeting of the new city council on 10 January, one of the new councillors,
William Wilson, was elected chairman. In September 1869, Bishop stood for election as a city councillor and was successful. In the following year, he produced an abstract of the Municipal Corporations Act so that citizens could inform themselves of the workings of city councils. Towards the end of his term as mayor,
Henry Sawtell fell ill and could not fulfil his functions. Councillor Bishop filled his place during that time. The election of the next mayor was held on 18 December 1872, but
The Press, the local Christchurch newspaper, already reported on 14 December of Councillor Bishop as mayor-elect. The election took place on the agreed date, and Bishop was elected unanimously. In those days, the councillors elected one of their group as mayor, i.e. the position was not elected at large (by the voting public) as is the case today. On the evening of his election, Bishop gave a banquet for 50 people at the
Clarendon Hotel, with those present representing the who is who of colonial Christchurch. At the Christchurch City Council meeting on 17 December 1873, Bishop as outgoing mayor was thanked for his service and presented by the city councillors with a gift. The councillors then proceeded to elect the next mayor from their midst. Councillor Calvert proposed
Michael Hart as mayor, as he had shown administrative skill as the chairman of the works committee. Councillor
Fred Hobbs seconded the motion and Hart was elected unanimously. Whilst
Christchurch City Libraries lists the 7th mayor, Michael Hart, as the one who gave the first link to the Christchurch
mayoral chain, this tradition was in fact started by
Henry Sawtell, who gave the first link on the day his successor, Edward Bishop, was chosen. who was thus the third person to add a link to the mayoral chain. Bishop's term as a city councillor expired in September 1875, when he did not stand for re-election. He had first acted as
returning officer for the Christchurch City Council on special appointment by the
Superintendent,
William Rolleston, in September 1874. At the time, it was feared that the mayor, Michael Hart, would stop the election from going ahead, and Bishop's appointment was to counter that. After his retirement from political office, he was appointed as returning officer for further for Christchurch City Council elections; his next engagement was for the mayoral election in December 1875. The Municipal Corporations Acts Amendment Act, 1875, was passed, and this legislation stipulated that mayors had to be elected at large (i.e. by eligible voters). The incumbent,
Fred Hobbs, was the only candidate nominated, so Bishop declared him elected unopposed on 17 December 1875. Bishop was succeeded as returning officer for mayoral elections in December 1876 by
Leslie Lee. ==Other activities==
