Picture a home support worker doing three visits before lunch. Showers, medication, breakfast, a chat that might be the only conversation her client has today. She is one of 293,316 New Zealanders whose main income came from health care and social assistance in 2024, the most recent year Stats NZ has published (Source: Stats NZ, earnings-by-industry).

That matters this week, because the way that work gets funded is under active dispute. A health trust has told RNZ that changes to home care contradict advice given to the minister, as reported by RNZ. The argument is about contracts and models of care. The data underneath it is about a workforce that has grown faster than almost anything else in the economy.

Here is the number that stopped me. Between 2023 and 2024, the count of people earning their main income in health care and social assistance rose by 14,538. Go back through all 24 years of the series and there is no bigger single-year increase. The next closest is 2022, at 13,584. Most years this century the sector added somewhere between 3,000 and 7,000 people. The last three years have been a different gear entirely.

Zoom out further and the scale becomes obvious. In 2000, 142,698 people drew their main income from this industry. The 2024 figure is more than double that. The sector added 75,525 people between 2000 and 2014, then another 75,093 in the ten years to 2024. Same volume of growth, packed into four fewer years.

The pandemic-era acceleration is the clearest break. From 2000 to 2019 the sector grew by an average of about 5,500 people a year. Since 2019 it has added 45,258 people, an 18 percent lift in five years, or roughly 9,000 a year. Whatever else the last half-decade did to New Zealand, it pulled tens of thousands more people into paid caring work.

Now the honest caveat. This is a count of people, not hours. Someone working six hours a week on a home care roster counts the same as a full-time hospital nurse. If the sector has been splitting shifts more finely, or leaning harder on part-time and casual rosters, the headcount can rise faster than the actual care being delivered. Definitional and coverage changes in tax-linked data can also nudge a series. And 2024 is the latest year available, so none of this captures what has happened in the eighteen months since.

Even allowing for all of that, the direction is not ambiguous. An ageing population needs more care, and the number of people paid to provide it is climbing at a rate the country has not seen before.

My view: that makes home care contracting one of the highest-stakes administrative decisions in government. When nearly 300,000 people's main income sits in one sector, a change to how the work is bought is not a procurement tweak. It is wage policy for a workforce the size of Christchurch.
