Does Te Paati Maori’s ‘Overhang Strategy’ make sense?

Splitting the vote worked once by accident. Trying it on purpose is a very different, riskier game.

  Te Paati Maori has told supporters to give their electorate vote to its own candidates in all seven Maori seats and take their party vote elsewhere, to Labour or the Greens, launching its campaign in Gisborne on that single message. It is a deliberate attempt to engineer what MMP wonks call an overhang: winning more electorate seats than a party's share of the party vote would otherwise earn it.

  I flagged this exact scenario in April, months before Rawiri Waititi and Debbie Ngarewa-Packer said it out loud, in an analysis of National's own overhang exposure. The question worth testing now is whether the tactic actually works, and whether it could backfire the way the last one did.

  An overhang is not new, and its record for Maori is mixed.

In 2005, a four-seat Maori Party overhang helped produce a Parliament so tight that Winston Peters ultimately chose Helen Clark's Labour over Don Brash's National, handing Clark a third term.

In 2008, a two-seat overhang sat alongside a confidence-and-supply deal with John Key that put Pita Sharples and Tariana Turia into ministerial office.

In 2023, six electorates on just over three per cent of the party vote created two more overhang seats, yet Peters again held the balance and chose National and ACT. The overhang did not buy Te Paati Maori a seat at the Cabinet table. It bought Peters the leverage, and he spent it elsewhere.

  The mechanism is constant even when the outcome is not. Every overhang seat raises the bar for a majority, two MPs at a time. The more electorates Te Paati Maori holds beyond its party-vote entitlement, the bigger Parliament gets, and the harder it becomes for either bloc to govern without a third party in the room.

  That third party may not be Peters this time.

The latest 1News-Verian poll has Opportunity, formerly The Opportunities Party, level with New Zealand First on eight per cent, having sat under five per cent for most of the year. A Taxpayers' Union-Curia poll already puts it across the threshold. Clear five per cent, and Opportunity becomes the kingmaker Te Paati Maori's strategy was never built to create for someone else.

  Here is the deeper problem.

Te Paati Maori's overhang will not be the only one in play. I documented in April how National, on roughly 30 per cent of the party vote, is tracking to hold far more electorates than that share would proportionally deliver, through the identical mechanic: coalition voters parking their party vote with ACT or New Zealand First while still ticking the familiar blue name locally.

Add fast-track approvals biting in marginal seats, civil service cuts, and a boundary review that has shifted Hutt South and Maungakiekie leftward, and several National electorates are genuinely live.

  Two overhangs pulling in opposite directions do not cancel out. They compound.

A Parliament stretched to 128 or 130 seats needs 65 or 66 votes for a majority that neither bloc can comfortably muster on current polling.

  I have watched this play out before. In past elections, John Tamihere and Willy Jackson toured marae explaining the split-vote logic, largely unreported by mainstream media. I took calls from kaumatua from Northland to Otago asking what an overhang meant, and was the only commentator to call it correctly. I called this year's overhang too, National's, before either major party said a word about it publicly.

  Labour, campaigning on ‘two ticks Labour’, is betting Maori voters will conclude a strong, unified vote beats a clever, split one.

Maori roll voters have shown for two decades they understand MMP better than most commentators do. But an overhang built on principle can just as easily hand power to a party Te Paati Maori never intended to empower, as 2017 and 2023 showed.

On present numbers, it could happen again, only this time the kingmaker might be a 38-year-old economist nobody saw coming.

Te Paati Maori is playing the smartest hand in MMP. It just is not the only player at the table holding the same cards.
