It has been difficult for Willis to completely rein in spending at a time the economy has needed support.
In the eyes of Treasury Secretary Iain Rennie, Willis has not truly started consolidating the finances.
Treasury will publish fresh economic forecasts at 1pm on Tuesday in its Half-Year Economic and Fiscal Update (Hyefu). New Zealand Debt Management will also provide an updated forecast bond issuance programme, while Willis will preview Budget 2026 via the release of her Budget Policy Statement.
Economists believe the documents will show little change from the Budget in May.
They see Obegalx – the new, rosier method the Government is using to calculate the surplus/deficit that excludes the impact of ACC – to move out of the red by 2028/29, if not a year later.
The Government’s goal, which it set in 2024, was to bring this measure back to surplus in 2027/28.
The fiscal plan National took to the election had the books getting back to surplus, using the traditional Obegal (operating balance before gains and losses) measure that includes ACC, by 2026/27.
The Obegal deficit sat at $5.2 billion in October, according to the Government’s latest monthly accounts.
In May, Treasury didn’t have the Obegal returning to surplus within its four-year forecast period.
Last week, Willis said she would stick to her plan to increase operational expenditure by $2.4b in Budget 2026.
She noted that in prior Budgets, she had spent less than she had signalled.
To put $2.4b in context, former Finance Minister Grant Robertson had an operating allowance of $4.8b in his final Budget in 2023.
Willis is yet to confirm how much will be set aside for capital expenditure.
Economists believe the Government will broadly maintain the bond issuance programme it published in May, which forecast it issuing $132b of New Zealand Government Bonds in the four years to 2028/29.
The Government is issuing a lot more debt than it did pre-Covid, when it issued about $8b of bonds a year.
It is currently renewing its Covid-era debt, which it is unable to pay off, all the while issuing new debt to pay for new initiatives and cover its interest bill, which is worth about $9b.
Quantitative tightening, or the unwinding of the Reserve Bank’s money printing programme, is also requiring the issuance of more debt.
Net core Crown debt hit 43% of gross domestic product (GDP) in October, according to the latest monthly Crown accounts.
The Government has committed to putting debt to GDP on a downward trajectory towards 40% and keeping it below this level in the longer term.
Pre-Covid, net core Crown debt was worth less than 20% of GDP.
Because economists don’t expect to see major surprises in Treasury’s new forecasts, they don’t believe the forecasts will change the way the Reserve Bank sets monetary policy/the OCR.
