Labour has spent $302,181 on Meta ads over 90 days, with $276,070 of it in the past 30 days. Its last month alone roughly matches the combined 90-day totals of Act, NZ First and National. In the final week of a close election, Labour has turned Facebook and Instagram into a paid-reach contest and outbid the entire coalition.
That is a legitimate campaign choice. But the money is not buying what most people assume it buys. It is buying entry into Meta’s ad auction, where an AI system, not the party, makes the final call on who sees what. Every business running paid social is in the same position.
A month of money, one platform
The gap is stark. National has spent $121,000 over 90 days without ramping up, and the Greens $94,111, according to Newsroom’s analysis of Meta’s Ad Library. National is leaning instead on unpaid viral and AI-generated content, a playbook Newsroom notes is not delivering the polling lift it produced in 2023.
Put Labour’s figure against the rules. The legal cap is $1.503 million per party for the party vote, so roughly 20 percent of Labour’s permitted spend has gone into one platform in one month. That sits on top of the state-funded broadcasting allocation of $4,145,750, where Labour received $949,566 against National’s $1,122,209. The allocation was varied in August after two parties missed registration before the regulated period.
This is not unprecedented in absolute terms. In 2023, Act put up to $905,000 into social platforms in the final three months, far more than anyone has reported this cycle. What stands out in 2026 is how lopsided the spending is.
The surge was planned, not panicked
This was no last-minute spike. By 21 October, The Post had found Labour spending $135,000 in a single week, more than eight times National’s $15,820. One 15-second YouTube spot, “Don’t Risk 3 More Years”, cost about $33,000. Labour had run 562 ads against National’s 304, with NZ First on 511.
Labour ran no ads a week into the campaign and then went all-in. Holding fire and concentrating spend where attention peaks is a textbook media strategy, and plenty of retailers run Black Friday the same way. The interest-based targeting clusters around renters, first-home buyers, parents and renewable energy. That is a clear audience bet.
Targeting is a request, not an instruction
This is where the story matters for anyone with a marketing budget. RNZ found that of more than 500 National ads, 92 were seen only by men, with some reaching 3.9 million views. Just one reached only women, for a single day. National said it did not set ads up that way. The Greens showed the reverse pattern.
The cause is Meta’s machinery. Its Andromeda AI narrows tens of millions of possible matches to a few thousand before ranking them, and Advantage+ tools can automate targeting, budget and placement whatever the advertiser originally chose.
Katherine Jensen, a Professional Teaching Fellow at the University of Auckland Business School, points to research showing delivery skews by gender and race even with inclusive settings. A 2024 European Parliament analysis of 110,000 ads found men were more likely to be served populist party ads. And reaching less sympathetic voters can cost two to three times more. The algorithm optimises for engagement, which means it quietly steers money towards people already inclined to click.
For a business, that is a direct cost problem. If you are paying to reach new customers, the platform may be spending your budget on the ones you already have.
Mandating transparency could switch the tap off
The obvious answer is disclosure rules. Jensen argues New Zealand urgently needs parties to publish targeting settings and platforms to publish delivery data. The EU tried exactly that from October 2025. Meta and Google did not comply. They stopped carrying political ads in the EU altogether.
That should give any future Wellington regulator pause. Well-intentioned rules that prompt withdrawal do not produce transparency, they produce a market with fewer options. TikTok already bans paid political advertising outright, so presence there is purely algorithmic.
Meanwhile the money keeps flowing offshore. Newsroom describes the most febrile final week since the Exclusive Brethren, with paid influencers and leaflet drops adding to the noise.
The lesson outlasts election day
Whoever wins on Saturday, the campaign has shown how New Zealand advertising works now. A capped, publicly overseen election is being fought substantially inside a foreign platform’s auction, with outcomes even the biggest spender cannot fully dictate.
Businesses should take note. Audit what your campaigns actually delivered, not what you asked for. Treat automated targeting as a hypothesis to test. And when the transparency debate reaches Parliament after the election, push for rules that improve accountability without pushing the platforms out of the market.
