The Budget Economic and Fiscal Update released on 28 May tells a more reassuring story than the Half Year Update did in December.¹ Deficits narrow earlier. The cyclically-adjusted OBEGALx — the measure favoured by Finance Minister Nicola Willis, which strips ACC’s volatile revenue and expenses out of the historical OBEGAL — returns to surplus in 2028/29, a year sooner than previously forecast.² Tax revenue holds up, and on the Treasury’s fiscal-balance measure, policy keeps supporting demand through 2026/27 before tightening from 2027/28.³ It rests, though, on a sharp recovery: real GDP growth lifting from 1.2% this year to a peak of 3.2% by 2028, unemployment easing from 5.5% to 4.3%, and net migration rebuilding — each plausible alone, but the recovery needs most of them to arrive together and on schedule.⁴ It is, on the surface, a better-than-expected set of numbers. The trouble is what sits underneath them.
Inflation is the assumption that should give most pause. It doesn’t so much behave as lurch: CPI surges to 4.0% this year — partly higher fuel prices from offshore conflict — before the forecast has it dropping abruptly to 1.6% in 2027, then settling near 2%.⁵ That near-halving in twelve months is a heroic call, more so when you separate out domestic, non-tradeable inflation, which Stats NZ measured at 3.5% in the year to March, with electricity up 12.5% and council rates up 8.8%.⁵ Ask anyone who has opened a rates letter, renewed an insurance policy or braced for another winter power rise. The squeeze households feel is not the tidy headline figure the forecast leans on — and a great deal rests on it, because inflation feeds wages, interest costs and the tax take alike.
The forecasts also assume the Government delivers ambitious savings tracks at Health New Zealand, Kāinga Ora and the Ministry of Social Development.⁶ Every line of the recovery needs something to land perfectly — and the cost pressures are neither theoretical nor distant. Defence needs roughly $6 billion over the next two Budgets, the Health Infrastructure Plan more than $20 billion over the decade, school property a significant uplift, with Treaty relativity and pay equity settlements live alongside them, and adverse weather a recurring fiscal risk the Treasury rates as reasonably possible at least once every four years.⁶
Nowhere is the pressure clearer than New Zealand Superannuation, forecast to climb from $24.7 billion this year to $31.2 billion by 2029/30 — about $1.6 billion more each year, the single largest driver of core Crown expense growth, roughly half of it simply more people turning 65.⁹ Against that, the welcome decision to recommence Super Fund contributions looks light on plan for what is, on any honest reading, the largest looming fiscal pressure of the next two decades.
All of which prompts a fair question: why not go harder, sooner? With the deficit peak pushed out to 2026/27 and surplus not arriving until 2028/29, the consolidation looks notably gradual. Former Finance Minister Steven Joyce has made the point bluntly, arguing the Government could have moved faster on public-sector restraint — noting core public servant numbers have climbed from about 49,000 in 2017 to 64,000 today without an obvious lift in output.¹⁰ His explanation is political: in a coalition, the things you think should have happened sooner are often slowed by negotiation between the parties. Whatever the cause, two and a half years in, the heavy lifting still sits mostly in the forecast years rather than behind us.
That is the sobering side. There is a more encouraging side too. The tax package is sensibly targeted. Lifting the Foreign Investment Fund de minimis threshold from $50,000 to $100,000 of shareholdings, and allowing the revenue account method for unlisted shares held by any New Zealand resident, removes a real barrier to migration for skilled people and cuts compliance costs for ordinary investors caught in rules built for complex international structures.⁷ Changes to charities and not-for-profit settings — including a $100,000 annual cap on individuals’ rebate claims — tidy up a system that had drifted from its purpose.⁷
Not everything is so easily defended. One genuine outlier is the Emerging Managers’ Programme — a scheme backing first-time and emerging fund managers who invest in startup companies, to help those funds build scale and a track record.⁸ Read that twice. The Crown is, in effect, backing unproven managers backing unproven companies, stacking emerging-manager risk on early-stage venture risk. The mind boggles slightly. There is a rationale — New Zealand’s venture ecosystem is thin and the next generation of managers must come from somewhere — but it sits oddly in a Budget otherwise sold on discipline, and the guardrails will be worth watching.
So this is a Budget Update that asks New Zealanders to take a fair amount on faith: that growth returns on cue, that inflation halves to target while domestic prices still bite, that savings targets are met, and that events outside the Government’s control stay kind. The genuine wins deserve acknowledgement, and the risks deserve to be taken just as seriously. The Treasury has done its job — it has shown us the figures and told us plainly what could go wrong. The question is whether the rest of us are reading both halves of the document.
