The 1889 Wellington City mayoral election was part of the New Zealand local elections held that same year to decide who would take the office of Mayor of Wellington for the following year.
After a popular term in office the incumbent mayor, John Duthie, surprisingly declined to seek re-election. There was speculation that former city councillor Kennedy Macdonald (who retired in Duthie's favour at the previous election) would stand to succeed him as mayor, though he did not.[1] After a period of uncertainty over whether any candidates would come forward at all, Charles Johnston, the former member of parliament for, was nominated. Ultimately he was the only candidate nominated and thus was declared elected unopposed.[2] It was the second mayoral election in a row where the mayoralty was uncontested.
