The 1977 Porirua mayoral election was part of the New Zealand local elections held that same year. The elections were held for the role of Mayor of Porirua plus other local government positions including fifteen city councillors, also elected triennially. The polling was conducted using the standard first-past-the-post electoral method.
The incumbent Mayor, Whitford Brown, sought re-election for a sixth term. In 1975 Brown had been caught and convicted of driving under the influence of alcohol. He spent time afterward, including during the election campaign, in treatment for alcoholism at Hanmer Springs. Four councillors challenged him including two official party candidates from Labour and the Values Party. Brown had been an active Labour member in the past and was endorsed by Labour in all previous elections. Two other former Labour ticket councillors (Ted Taylor and Rex Willing) also challenged Brown.[1] For standing as an independent against the official Labour ticket, Willing was later expelled from the party.[2]
