Porirua City Council will hold a by-election in October to fill a council seat vacated by the sudden death of councillor Mike Duncan.
The Onepoto General Ward seat is one of five representing eastern and western Porirua. Nominations open 9 July and close 6 August, with voting papers to be posted from 14 September. Ballots must be returned by midday 16 October.
Deputy electoral officer Jack Marshall said Duncan's replacement would have "big shoes to fill" but full representation was for the city's future decisions.
