Petone is a former parliamentary electorate in the lower Hutt Valley of New Zealand, from 1946 to 1978.
The 1941 New Zealand census had been postponed due to World War II, so the 1946 electoral redistribution had to take ten years of population growth and movements into account.
[1] The electorate was based on the southern part of the city of Lower Hutt.
Settlements within the electorate included the suburb of Petone, Wainuiomata, and Eastbourne.
Its first representative was Mick Moohan of the Labour Party, who was Minister of Railways from 1957 to 1960 while serving the electorate.
