The data suggests both are right - sort of
Start with what the numbers actually show. The TELUS Health Mental Health Index for Q1 2026 found that New Zealand businesses are losing up to 94 working days per worker annually to mental health challenges. Nearly four in ten workers frequently feel anxious. Mental health conditions now drive nearly a third of income protection claims in New Zealand, according to MoneyHub.
Big numbers. Except they haven't moved. The national mental health score has sat at 60.6 for multiple consecutive periods - strained, yes, but unchanged despite years of growing EAP spending, wellbeing programmes and awareness campaigns. More money in. Same numbers out.
Compare that with the rest of the world. Canada's score is 63.1 - its own researchers call that near-crisis. Australia has hit a four-year low. South Korea is in the mid-50s. New Zealand isn't doing well. But it also isn't falling. And that flatline, it turns out, is one of the more interesting pieces of data available to New Zealand employers right now.
The question managers have been afraid to ask
John Burn-Murdoch, the Financial Times's chief data reporter, published an analysis this week that puts a number on something many New Zealand managers have suspected but wouldn't say out loud.
He found that across the UK, US and internationally, the share of young people reporting a mental health problem has risen steeply over the past decade. The share who say that problem actually limits what they can do day-to-day has barely moved. In England, researchers Christoph Henking and Ben Baumberg Geiger found a steep rise in young people reporting mental illness alongside a functional limitation rate that has barely shifted. Two measures of the same population, going in completely different directions.
The finding that cuts closest to home: when young people were asked whether someone experiencing "broad happiness but occasional moments of worry, frustration or loss of confidence" has a mental illness, more than half now say yes. A generation ago, one in five said the same. Older people's views haven't changed.
Put plainly: the difficult quarter, the demanding boss, the project that goes sideways, the anxiety of being new somewhere - experiences that older workers managed without calling them mental health events - are now routinely being described by younger workers in clinical language. The experiences may be similar. The vocabulary is completely different.
There's another data point worth sitting with. The rise in reported mental health problems is significantly higher among people who identify as politically left-leaning than right-leaning. But that gap disappears entirely when you ask the same question about physical health. Which means the divergence isn't about who's actually suffering more. It's about which groups have adopted clinical framing and which haven't.
This doesn't mean younger workers are making it up
To be clear about what the research does and doesn't say: it isn't arguing that young workers are fine or that their distress is fake. Self-harm hospitalisation rates among teenage girls and young women climbed sharply through the 2010s in multiple countries. That's real, clinical, and alarming.
What it does say is that most of what's showing up in New Zealand's absence data and claims statistics sits somewhere between that acute clinical reality and what previous generations would have called a rough patch. And those two things require different responses.
New Zealand's Gen Z workers score lower on every TELUS mental health measure than their older colleagues. They're the most anxious, most likely to report burnout, most likely to take mental health leave. Forty-three per cent say mental health is negatively affecting their work productivity, against 31 per cent across the workforce as a whole.
At the same time, eight in ten Gen Z workers globally say their goal is to reach the top of their field - a higher share than millennials or Gen X at the same stage. More than half respond to out-of-hours messages immediately. This isn't a generation that's checked out. It's a generation that's ambitious, engaged, and - this is the critical part - describes its internal experience in a very different vocabulary to the one their managers grew up with.
Sixty-four per cent of New Zealand Gen Z live paycheque to paycheque, against 52 per cent globally. They're under more financial pressure than their peers in comparable economies. But when asked whether they feel stressed or anxious all or most of the time, 47 per cent say yes - broadly in line with global peers rather than proportionally higher. The clinical language and the underlying condition are not tracking together the way you'd expect.
The system is part of the problem
Burn-Murdoch has a name for the mechanism: "systems medicalisation." The basic idea is that workplace and benefits frameworks only offer one pathway to formal support - a clinical label. If the only way to get help is to call something a mental health condition, more people will call it a mental health condition. The system is generating some of the caseload it was designed to address.
This creates a problem that most New Zealand workplaces haven't yet figured out. A manager in their 40s who pushed through a difficult period at work without clinical framing is now being asked to manage someone for whom that same experience might genuinely feel like, and might genuinely be described as, anxiety or burnout. Both people may be experiencing something real. They're not talking about it in the same language. And that mismatch is driving friction on both sides.
Three in four managers globally say Gen Z is harder to work with than any previous generation they've managed. Nearly 40 per cent, according to FranklinCovey research in 2025, would rather hand a task to an AI tool than work through it with a Gen Z employee. That's not evidence of a generation that's failed. It's evidence of a communication breakdown between two generations applying completely different frameworks to the same working life.
Many of today's youngest workers came into the workforce during or straight after a period of workplace isolation. They missed the informal social transmission that offices quietly provide - watching how a senior colleague handles a difficult client, hearing how someone talks about a hard week without making it a crisis, learning what's worth naming and what's worth absorbing. PwC UK recognised this directly, launching a resilience training programme specifically for its 2025 graduate intake.
What to do with a flatline
If the rise in mental health claims reflected genuine and worsening clinical deterioration, New Zealand's scores would keep falling. In Australia, they have. In New Zealand, they haven't. The plateau - 60.6, unchanged, persistent - suggests the labelling shift has settled into something relatively stable, while the management and communication conditions underneath it haven't improved.
Only 4 per cent of New Zealand workers said senior leadership support for work-life balance had become much more supportive over the past year. Nineteen per cent didn't believe their leaders could maintain healthy work-life boundaries themselves. More than half were unsure whether their employer even offers an EAP, despite most larger employers providing one.
The investment exists. The conditions around it don't. Clinical provision sitting on top of an unchanged management culture produces unchanged scores.
Mental Health Minister Matt Doocey's workplace toolkit for small and medium businesses at least recognises this - its value is in normalising the conversation before a clinical threshold is reached, rather than waiting for a claim to land.
The harder shift is cultural. Managers who've quietly concluded that younger workers are just less resilient can be justified with one specific number from the FT analysis: functional limitation hasn't moved. The clinical reporting has. What's changed isn't primarily the scale of the suffering. It's what workers call it when it happens - and what, in turn, they expect their employer to do about it.
