The traditional tick-a-box voting system has been discarded by the Tauranga City Council in favour of a more complicated system in which voters will rank candidates in order of preference.
In a decision that Mayor Greg Brownless said came "out of the blue", the council agreed by an overwhelming majority to drop the First Past the Post (FPP) election system for the 2019 and 2022 elections.
The council voted 8-3 this week to replace FPP with the Single Transferable Voting (STV) system, with only Mr Brownless and councillors Bill Grainger and Terry Molloy opting to stick with the status quo.
The meeting was in total contrast to the five minutes it took the Western Bay District Council last week to decide to stick with FPP.
Eight of New Zealand's 78 councils used STV in the 2016 election. The council's decision could be reversed by a city-wide poll of registered voters, but that would need opponents of STV petitioning for a poll - requiring signatures from 5 per cent of Tauranga voters.
