Governing coalition parties have traded sharp words over an election overhang strategy, pivoting away from attacks on the opposition to fight among themselves. The tactical push encourages right-bloc supporters to split their votes between parties to maximize total seats, putting coalition partners at direct odds.
The dispute has drawn in former prime ministers, current ministers, and minor party leaders as campaigning intensifies ahead of a tight contest.
What sparked the strategy row
Separate campaigns led by billionaire Harry Mowbray and Reality Check Radio are encouraging right-bloc supporters to cast electorate votes for National while giving party votes to ACT or New Zealand First. The goal is to create an electoral overhang and secure extra seats in Parliament.
However, the tactic threatens to push top-ranking National list MPs and vulnerable frontbenchers like Paul Goldsmith and Chris Bishop out of Parliament. Both ACT and New Zealand First formally signed off on a full-page newspaper advertisement promoting the strategy written by former National and ACT leader Don Brash.
National pushes back as Key intervenes
National leader Christopher Luxon stated on Sunday that he completely disagrees with the strategy, warning it creates confusing messaging and risks allowing the Labour Party to form a government.
To protect Goldsmith's seat in Epsom against incumbent ACT leader David Seymour, former Prime Minister Sir John Key released a social media video urging Epsom voters to give Goldsmith their electorate vote while maintaining their party vote for National. Key previously maintained a cooperative arrangement with Seymour to ensure ACT's parliamentary presence.
ACT and New Zealand First hit back
ACT candidate Paul Henry criticised John Key's shift in stance as two-faced and arrogant, questioning how Key could contradict the message he promoted while in office. Henry also pointed to a letter from Goldsmith urging voters not to vote for Seymour, calling National's opposition to strategic voting hypocritical.
Meanwhile, New Zealand First leader Winston Peters defended the overhang strategy. Peters warned that a party vote for National would be wasted and labeled it astonishing that Luxon would discourage split voting under MMP.
What the dispute means for the election
The public fallout exposes deep friction within the right bloc over parliamentary survival tactics rather than policy differences. While minor parties seek to leverage the electoral system for maximum representation, National faces the risk of losing key ministers if voters follow the split-vote advice.
With Labour leader Chris Hipkins monitoring the constitutional implications of overhangs, the coalition infighting risks alienating voters and complicating the path to government formation.
What to watch: Watch whether right-bloc voters in Epsom and nationwide follow the split-voting advice or heed National's call for a unified two-vote loyalty.
