National and Labour Have More in Common With Each Other Than With Their Own Coalition Partners

Here is the uncomfortable truth nobody in Wellington wants to say out loud: the two parties that have spent a century pretending to hate each other now agree on almost everything that matters.

Watch what they actually do, not what they say. National cuts taxes a bit. Labour raises them a bit. Both accept the same fiscal framework, the same Reserve Bank mandate, the same trade agreements, the same untouchable superannuation age, the same Five Eyes commitments, the same basic shape of the welfare state. When one takes office, it trims the edges. When the other takes office, it expands them. The edges move. The centre never does.

The real ideological combat in New Zealand politics is no longer between National and Labour. It is between the managerial centre that both major parties now occupy and the four parties on the flanks who have noticed that the centre has stopped offering voters anything distinctive.

National isn’t the right-wing party anymore. ACT and NZ First are.

This is the shift the National Party itself hasn’t fully admitted. The party that fought elections on welfare reform and fiscal discipline now governs as a cautious centrist outfit that has accepted climate targets, Treaty-based co-governance arrangements, and most of the previous Labour government’s spending settings. Luxon’s National is not Key’s National, and it is nowhere near Bolger’s.

Which is exactly why ACT and NZ First have spent this term eating its lunch. They are competing for the right-wing ground that National vacated. Voters who want smaller government, less regulation, tighter immigration, or a fight over Treaty principles are not finding any of that on offer from National. They are finding it from David Seymour and Winston Peters, who have noticed the gap and walked straight into it.

The same thing is happening to Labour from the other direction. The Greens and Te Pāti Māori are pulling hard on wealth taxes, climate ambition, and constitutional reform. Hipkins is holding the centre. The flanks are where the energy is.

Why the grand coalition stops being unthinkable

Project the trend forward. NZ First builds a post-Peters structure and locks in 15 percent. ACT holds 10. The Greens push toward 15. Te Pāti Māori consolidates at 8 to 10. National and Labour each end up somewhere in the mid-twenties, staring at each other across a Parliament where neither can govern without three coalition partners who genuinely disagree with them on first principles.

At that point the arithmetic does the talking. A National-Labour arrangement — formal, informal, German-style, whatever you want to call it — stops looking like betrayal and starts looking like the only way to keep the lights on. Two parties that share a worldview governing together against four parties that don’t share it with them or with each other.

The activists will hate it. The donors will hate it. The press gallery will write a thousand columns about the death of two-party politics. And it will happen anyway, because the people who actually run National and Labour have far more in common with each other than either has with the partners currently sitting beside them in Cabinet.

The question nobody is asking

The interesting question isn’t whether National wants to keep governing with ACT and NZ First. It’s whether National still knows what it is when ACT and NZ First are the ones making the right-wing arguments.

A party that has lost its ideological centre of gravity doesn’t get it back by winning one more election. It gets it back by deciding what it actually believes — or it slowly merges, in everything but name, with the party it has spent a hundred years defining itself against.

That decision is coming. Maybe not in 2026. But it is coming.
