Special votes could swing New Zealand's 2026 election results

Special votes are used by voters who are absent from their registered electorate, are on the unpublished roll, live abroad, or enrol after the printed roll closed on 4 October. These ballots need a signed declaration witnessed by another enrollee and are subject to extensive checks, causing them to be counted up to ten times slower than ordinary votes. The Electoral Commission forecasts as many as 700,000 special votes for the 2026 election, a figure that could influence seat allocations, as seen in the last three elections where National lost seats and parties such as Labour, Te Pāti Māori and the Greens gained.

Younger, more mobile voters tend to submit special votes, which often favour left-leaning parties. The new enrolment deadline, set 13 days before the election, may increase the rate of disqualified special votes, adding uncertainty to the final result, which may not be confirmed for several weeks after polling day.
