Article #459
For decades I have written about the Budget from the outside. This year, I was fortunate enough to be there in person – in the lockup, with the Treasury’s forecasts and supplementary documents in front of me before the Minister rose to speak. There is value in having the source material itself, rather than seeing headlines that come after. What follows is my read.
The Budget Economic and Fiscal Update released on 28 May tells a more reassuring story than the Half Year Update did back in December.¹ Deficits narrow earlier. The cyclically adjusted OBEGALx, the operating-balance measure favoured by Finance Minister Nicola Willis as it strips ACC’s volatile revenue and expenses out of the historical OBEGAL, returns to surplus in 2028/29; a full year sooner than previously forecast.² Tax revenue holds up better than feared. And on the Treasury’s fiscal-balance measure, which tracks the actual cash impact of government on the economy, policy keeps supporting demand through 2026/27 before tightening from 2027/28 onwards.³
On the surface it is a better-than-expected set of numbers. As always, the trouble is what sits underneath them.
The forecasts assume real GDP growth lifts from 1.2% this year to a peak of 3.2% by 2028. This would be a sharp acceleration after three years of contraction or near-zero growth.⁴ They assume unemployment peaks at 5.5% and then drifts back down to 4.3%, and that net migration recovers towards its long-run average having run at barely a quarter of that recently. Each assumption is plausible on its own. The sticking point is that the recovery needs most of them to arrive together, and roughly on schedule.
Inflation is the assumption that should give readers the most pause. In these forecasts, it takes a less-than-linear, lurching path: CPI surges to 4.0% this year, driven in part by higher fuel prices flowing from offshore conflict, before the forecast has it dropping abruptly to 1.6% in 2027, then settling around 2%.⁵ That near-halving in twelve months is a heroic call. It looks more heroic still when you separate out domestic, non-tradeable inflation, the prices generated here at home, in services, rates and rents – 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 any local who has just opened a new rates letter, renewed an insurance policy, or braced for yet another ramp-up in winter power prices. The cost-of-living squeeze people are actually feeling is not the tidy headline figure the forecast leans on. And a great deal does rest on that figure, because inflation feeds wage expectations, interest costs and the tax take all at once. If domestic prices prove stickier than assumed, the path back to surplus gets harder.
The forecasts also assume the Government will deliver on ambitious savings tracks at Health New Zealand, Kāinga Ora and the Ministry of Social Development – all organisations that have run material operating deficits.⁶ Every line of the recovery requires for something to land more or less perfectly. The Treasury’s own statement of specific fiscal risks runs to dozens of substantial items; a catalogue of expensive surprises waiting to happen.⁶
Meanwhile, the wave of cost coming our way is neither theoretical nor distant. It is here now.
Defence capability needs roughly $6 billion in new funding over the next two Budgets just to deliver the existing plan. The Health Infrastructure Plan identifies more than $20 billion over the next decade. The school property pipeline signals a significant uplift. Treaty relativity payments and pay equity settlements remain live cross-portfolio risks.⁶
Nowhere is the pressure clearer New Zealand Superannuation. NZ Super payments are forecast to climb from $24.7 billion in 2025/26 to $31.2 billion by 2029/30, an average increase of about $1.6 billion every year. This is the single largest driver of core Crown expense growth, with roughly half of that uplift simply more people turning 65.⁹ Against that backdrop, the decision to recommence contributions to the Super Fund is genuinely welcome – but light on detail for what is, on any honest reading, the largest looming fiscal pressure of the next two decades.
That’s the sobering side. There is a more encouraging side too, and parts of it land particularly well for our Hawke’s Bay region.
The tax package is sensibly targeted rather than flashy. Lifting the Foreign Investment Fund de minimis threshold from $50,000 to $100,000 of shareholdings is a solid, practical move. Combined with allowing the revenue account method for unlisted shares held by any New Zealand resident, it removes a barrier to migration for skilled people and cuts compliance costs for ordinary investors – who should never have been tangled in rules built for complex international structures.⁷ The accompanying 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
But, not everything in the package is so easily defended. One such outlier is the Emerging Managers’ Programme, a scheme backing first-time and emerging fund managers who invest in startup companies, with the aim of helping those funds build capacity, scale and a track record.⁸ No, you’re not reading that wrong: the Crown is effectively backing unproven managers who are backing unproven companies, stacking emerging-manager risk on top of early-stage venture risk. The mind boggles slightly.
There is somewhat of a rationale behind it – New Zealand’s venture ecosystem is thin, exits like Xero and Rocket Lab show what is possible, and the next generation of managers has to come from somewhere. But it sits oddly in a Budget otherwise sold on discipline and rebuilding buffers, and it will be worth watching closely how the guardrails are drawn.
Closer to home, the Budget delivers tangible benefits to Hawke’s Bay. Cash-strapped, debt-laden councils such as Hastings stand to benefit from changes giving them a share of consents value, a scaling mechanism that better matches revenue to the growth that creates the work. Funds have been earmarked for design and enabling works at Hawke’s Bay Hospital, alongside the wider Regional Hospital Redevelopment Programme.⁶ There’s also a $400 million reserve fund for state highway resilience projects aimed at keeping critical routes open during severe weather – something Hawke’s Bay residents understand the importance of more than most. Cyclone Gabrielle is not yet three and a half years behind us, and the Treasury itself rates comparable events as reasonably possible, at least once every four years, within the forecast period.⁶
The bottom line? 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 the events outside the Government’s control stay kind to us. The genuine wins for investors, charities, regional councils, hospital patients and motorists on vulnerable routes, deserve acknowledgement.
The risks deserve to be taken just as seriously.
The Treasury has done its job. It has shown us the figures and, in the supplementary information, told us plainly what could go wrong. The question is whether the rest of us are reading both halves of the document, so there aren’t surprises down the road if certain elements don’t stick the landing.
