The history of New Zealand voting patterns suggests that, in normal circumstances, governments lose elections based on poor performances rather than winning on the rare occasions — like last time, over the Covid crisis — when the party in office was rewarded for what was perceived to be a meritorious effort during an abnormal time in our history.
Normally, the pendulum of public support swings only slightly, often not enough to remove the incumbent, and defeat at the polls usually only happens when voters just tire of those who occupy the treasury benches and vote for change.
The end result for an electorate such as New Zealand is that in most elections, the bulk of the votes are cast based on traditional ideological or social alliances of the individual.
So, in this country, it is rare to see dramatic swings of voter support within only one three-year cycle.
Traditionally, the government of the day is given the benefit of at least two concurrent three-year terms in office in order to give it time to fulfil its election promises.
