NHS staff looking at New Zealand? What three months of unused leave says about South Island hospitals

News · 2026-08-31 · 4 min read

If you work in the NHS, you will know what a stretched rota feels like. A new internal analysis from Health New Zealand's South Island region suggests hospitals there are under a similar kind of pressure, and that the usual vacancy numbers do not show the half of it. The real story is in the leave nobody can take, the overtime that never ends and the time-in-lieu that keeps piling up.

For nurses, doctors and allied health staff in the UK thinking about a move, this is useful reading, both as a sign of demand and as a guide to what to ask before you accept a job.

A shrinking workforce, with a caveat

The internal review finds the South Island's health workforce has shrunk considerably over the past four years, with the sharpest fall in the last twelve months. Health New Zealand itself is unsure how reliable that headcount is, though. A round of restructuring moved many support and public health staff from district payrolls onto national ones, so some of the missing workers may simply have been counted somewhere else.

That doubt is fair. It does not, however, explain away the leave and overtime figures.

Leave that cannot be taken

The average South Island health worker is holding roughly three months of unused annual leave. That is nearly double the next-highest region and more than five times what staff in Northland carry. Senior doctors are holding close to five months on average, triple the national figure for their colleagues.

This is not a case of people choosing not to take holidays. It points to a workforce that cannot be spared long enough to use the time it has already earned. Leave on that scale becomes a deferred liability: a cost that eventually lands through payouts, staff leaving from burnout, or both.

Overtime as the default

Nurses across the South Island carry most of the overtime hours logged in the region, plus a separate stockpile of unclaimed time-in-lieu. The balances have come down since 2022, but the analysis is clear about what that means: overtime has not gone away, it has become the normal way shifts get covered rather than a short-term fix.

Put simply, the system is using existing staff's unpaid or deferred hours to cover a permanent gap.

Where the job losses fell

Perhaps surprisingly, the decline was not mainly among nurses, doctors or midwives. Administrative, management and patient care-and-support roles fell the most. That may look efficient on paper, but the review warns that clinical staff are probably picking up coordination and support work that used to sit with others, adding friction for busy frontline teams.

The picture also varies across the region. Some districts grew their workforce over the period, while others, including some of the larger ones, shrank. The pressure is uneven rather than one blanket shortage.

What this means if you are weighing a move from the UK

A workforce that cannot take its leave is one where the shortage is already happening, just hidden in the payroll rather than the vacancy list. Bringing in overseas-trained nurses, doctors and allied health professionals is part of how health systems give tired teams room to breathe. That suggests real demand for experienced clinicians, but also that the first months in some teams could be busy.

Questions worth asking at interview:

• How is leave approved in practice, and how much do people in the team actually take?
• How often is overtime expected, and how is time-in-lieu handled?
• Which support and administrative roles does the ward or service have now?
• Is the district you would join growing its workforce or shrinking it?

If a UK police certificate is requested for your application, it comes from ACRO Criminal Records Office. Your UK documents are already in English, though certified copies may be needed. Visa options are on the Immigration New Zealand visa pages, and your rights as an employee, including leave, are explained on Employment New Zealand.

Reading between the lines

Whatever the final headcount turns out to be, the leave and overtime figures are hard to argue with. Three months of unused leave and overtime built into everyday rostering describe a workforce running beyond what it can sustain. For a UK clinician, that is both an opening and something to go into with your eyes open.
