Months of Untaken Leave: The Shortage Hiding Inside South Island Hospitals
News · 2026-08-31 · 5 min read
Staffing shortages in New Zealand's hospitals are not news. What is new is the evidence coming out of an internal analysis by Health New Zealand's South Island region. It suggests the gap is deeper than vacancy counts show, because it is being covered by staff who are not taking their annual leave, who are working unpaid overtime and who are building up time-in-lieu they never get to use.
If you work in nursing, medicine or allied health, or you are planning to move abroad for a healthcare job, here are the facts without the hype.
Start With the Leave Figures
Begin with the most important number. A typical South Island health worker is now holding roughly three months of annual leave they have not taken. Compare that with the rest of the country: it is nearly twice the balance in the region ranked next-highest, and more than five times what staff in Northland have stored up.
Senior doctors are worse off. Their average balance is close to five months, which is triple what the national figure shows for senior doctors.
Do not misread this as staff choosing to skip holidays. The plain truth is that rosters cannot spare them for long enough to go on leave they have already earned. When leave piles up like this, it stops working as a benefit. Workforce economists call it a deferred liability: a bill the organisation must pay at some point, as leave payouts, as burnout-related resignations, or both.
The Staff Numbers, and a Caveat
The review also looked at headcount. It found that the South Island's health workforce has fallen considerably across the past four years, with the biggest fall happening in only the last twelve months.
There is a caveat, and Health New Zealand raised it itself. Internal restructuring moved many support and public health staff from district-based payroll systems to national ones. So part of the missing workforce may still be employed in health, simply counted under a different payroll after being reclassified. The headcount figure, in other words, may not be fully reliable.
That is fair. It does not, however, explain away the leave and overtime records.
Overtime Is Now Part of the Roster
Nurses in the South Island hold most of the overtime hours logged across the region, and the total is huge. They also carry a separate store of time-in-lieu that nobody has claimed. These balances have come down since 2022. The internal analysis is direct about why that is not reassuring: overtime has not ended. It has settled in as a standard way of covering shifts, not a stopgap for a difficult season.
The difference matters. Short-term overtime helps a hospital handle a sudden spike. Permanent overtime means a fixed staffing hole is being plugged with the unpaid or delayed hours of people already on the payroll.
Admin and Support Roles Took the Biggest Hit
Here is a detail many will not expect. The decline did not mainly affect nurses, doctors or midwives. The steepest cuts fell on administrative, management and patient care-and-support positions. That can pass for efficiency on paper. The internal review warns that in reality clinicians are likely taking over coordination and support work others used to do, which adds friction for frontline teams already under strain.
Not Every District Is the Same
The numbers vary across the region. Some districts increased their workforce during the period studied. Others, including some of the bigger districts, recorded real falls. The pressure is uneven, not one blanket shortage across the board.
What Other Countries Should Learn
Health systems under long-running pressure often show this same build-up of unused leave and overtime, and workforce planners treat it as an early warning. That lesson applies to health authorities and staffing agencies far beyond the South Island. When workers cannot take leave they have earned, the shortage is not a future risk. It is already happening; it is just sitting in payroll records instead of on the vacancy list.
The original article argues that organisations recruiting healthcare professionals internationally should move before burnout-driven exits make the shortage worse. Its view is that hiring overseas-trained nurses, doctors and allied health professionals does more than fill today's open roles: it gives exhausted staff space to take their earned leave before tiredness becomes resignations.
Straight Talk for Health Workers Abroad
Whatever the verified headcount ends up being, the leave and overtime data are difficult to dismiss. Three months of unused leave plus overtime that is built into the roster points to a workforce stretched past a sustainable limit, however the org chart is arranged. The open question for health leaders and the recruiters who work with them is how fast fresh capacity can arrive before deferred leave becomes a wave of departures.
If you are a health professional in Nigeria or anywhere else following these trends, do your homework. Check job offers and registration steps through official sources, and remember that a genuine employer will never ask you to pay for a job offer. Real demand is a reason to prepare properly, not a reason to rush.
