The 1927 Petone Borough Council election was a local election held on 27 April in the Petone, New Zealand, as part of that year's nation-wide local elections. Voters elected the Mayor of Petone and nine borough councillors for a two-year term. Polling booth voting and the first-past-the-post voting system were used.

Background The incumbent mayor, John William McEwan, declined to stand for a fifteenth term in office. Two candidates emerged to replace him.

Candidates George Cook George Cook, the owner of a manufacturing company, had been a Petone Borough Councillor since 1919 and a member of the Petone Fire Board since 1920. After declaring his candidacy, Cook underwent a minor operation though it was not to effect his ability to campaign. He announced his candidature after John William McEwan had indicated he would not stand and was backed by the Civic Association.

David McKenzie David McKenzie was a Scottish-born trade unionist and former employee of the Petone Woollen Works who had led a strike for better working conditions in 1916. He had previously been a borough councillor from 1915 to 1918. He had stood previously for mayor in 1921 against McEwan. Despite his long association with the Labour Party and trade unions, he ran as an independent candidate.
