Cutting Through the Noise
There is a lot of noise around government spending, debt, and who is responsible for what. Most of it comes from people mixing annual spending, total debt, and political framing without separating what is structural, what is emergency, and what is long-term obligation.
To understand it properly, you have to separate three things: what the government spends each year, what it earns each year, and what it has accumulated in debt over time. Once you do that, the picture becomes a lot clearer.
The Income Side of the Equation First
Before looking at spending and debt, it is important to understand the size of the income base that supports the system.
Government revenue in New Zealand comes mainly from income tax, GST, company tax, and other duties. In the early 2010s, total Crown revenue was roughly 60 to 70 billion dollars per year. By the late 2010s, this had grown to around 80 to 90 billion dollars. Today, government revenue sits in the range of roughly 165 to 175 billion dollars per year depending on the fiscal year measured.
This means government income has approximately doubled over the same broad period in nominal terms.
This growth has been driven by population growth and net migration, wage growth and inflation increasing tax bases, higher GST revenue from higher prices, expansion of the corporate tax base, and overall economic growth in exports and services. At the same time, New Zealand’s wider economy has also expanded significantly, with nominal GDP increasing strongly over the same period.
This matters because government debt is always measured against the size of the economy and revenue base, not in isolation.
Starting Point – What the System Looked Like Before COVID
Before COVID, New Zealand was not operating a 180 billion dollar spending system.
In the years leading up to 2019, government spending sat roughly in the range of 120 to 130 billion dollars per year. At that time, net core Crown debt was around 60 to 70 billion dollars depending on the exact year and measure used.
That was not a zero starting point. It was already the result of decades of gradual borrowing across multiple governments.
The COVID Shock – Where the System Changed Scale
COVID was the largest fiscal shock in modern New Zealand history.
During 2020 to 2022, government spending increased sharply due to emergency measures including wage subsidies, health response costs, border controls, and broad economic support. Treasury estimates place the total COVID fiscal response in the range of roughly 60 billion dollars across multiple years.
That spending was funded through borrowing and absorbed into the Crown accounts over time. At the same time, tax revenue dropped due to economic contraction, which increased borrowing further.
This combination drove debt up rapidly from roughly 60 to 70 billion pre-COVID to well over 140 billion within a few years.
Post-COVID – What Actually Changed
Once the emergency phase ended, spending did not return to previous levels. Instead, it stabilised at a higher permanent baseline.
This is because most government costs are structural rather than temporary. Health costs rose due to demand and staffing pressure, public sector wages increased due to inflation, superannuation rose with an ageing population, and debt interest costs increased due to higher borrowing and interest rates.
This is why annual spending moved from around 120 to 130 billion before COVID to roughly 170 to 185 billion after COVID and inflation effects. It is not a redesigned system. It is a permanently higher cost base.
Where We Are Now – The Current System
Today, New Zealand operates at a government spending level of roughly 180 to 185 billion dollars per year.
Revenue sits slightly below spending, resulting in annual deficits in the range of roughly 10 to 15 billion dollars. That gap is what continues to add to debt each year.
Net core Crown debt is now around 180 billion dollars.
Debt Servicing – What People Often Miss
The government pays interest on the entire debt stock, not just recent borrowing.
At current levels, interest costs are roughly 8 to 10 billion dollars per year depending on interest rates. That is around 700 to 850 million dollars per month.
This cost is applied across the total Crown debt pool, not separated by government or event.
The Real Comparison That Matters
The current government is running annual deficits in the range of roughly 10 to 15 billion dollars.
At the same time, debt servicing costs are roughly 8 to 10 billion dollars per year.
In simple terms, what is being borrowed annually is close in scale to the cost of maintaining the existing debt.
Who Actually Built the Current System
The current 180 billion dollar system was not created by one government.
It has developed over time through successive governments increasing health and welfare spending, earthquake recovery spending, the COVID emergency response, inflation-driven wage and service cost increases, an ageing population increasing superannuation and healthcare demand, and ongoing deficits across multiple political cycles.
On top of this are long-term statutory and contractual commitments that continue regardless of government. These include Treaty of Waitangi settlement obligations, compensation and redress arrangements, superannuation entitlements, long-term infrastructure contracts, and legislated policy commitments.
Each government inherits both the spending system and these binding obligations. A large share of spending is structurally committed each year and is not easily adjustable in the short term.
The Simple Truth Under All the Numbers
New Zealand moved from a roughly 120 to 130 billion dollar annual spending system before COVID to a roughly 180 billion dollar system after COVID and inflation.
Debt moved from roughly 60 to 70 billion before COVID to around 180 billion today due to crisis borrowing and long-term structural deficits.
Annual deficits continue across governments, meaning debt continues to grow.
Debt servicing now costs close to 10 billion dollars per year, creating a permanent structural expense.
At the same time, government revenue and national income have also grown significantly, meaning the system is larger on both sides of the ledger.
Final Thought – In Simple Terms
What people experience today is not the result of one government in isolation.
It is the accumulation of decades of decisions layered on top of a major global shock that permanently shifted the cost base of the state.
No single government created the current system. They have all operated within it, adjusted it, or added to it, but none started from a blank sheet.
The real issue is not just how much is being spent or borrowed.
It is how much of that spending is structurally locked in, and how much flexibility remains inside a system that now operates at roughly 180 billion dollars a year, with a significantly larger income base but also significant long-term obligations.
