The 1921 Wellington City mayoral election was part of the New Zealand local elections held that same year. In 1921, elections were held for the Mayor of Wellington plus other local government positions including fifteen city councillors. The polling was conducted using the standard first-past-the-post electoral method.
The long serving incumbent Mayor John Luke did not seek re-election. To replace retiring Mayor Luke five "anti-Labour" candidates emerged, which caused fear of vote splitting and a repeat of the 1912 election. As such, two immediately withdrew and the remaining three agreed to submit to the decision of an impartial committee to decide which one of them was most suitable.
The three aspirants for the Civic League nomination were:[1]
Thomas Hislop, a former mayor from 1905 to 1909, also intended to stand as an independent candidate, eschewing the Civic League's nomination process.[1] However after receiving multiple requests Hislop decided to withdraw from the election.[2]
The Labour Party selected Pat Hickey as its mayoral candidate. Hickey was the editor of the Maoriland Worker newspaper.[3]
Wright defeated Hickey for the mayoralty in a two horse race. The election was also notable due to the success of Annie McVicar, who became the first woman to be elected as a city councillor in Wellington's history.
