New Zealand’s Private Healthcare Shift Needs a Plan

Access to public elective services in New Zealand has long fallen short of what patients need. Hip replacements, cataract surgeries, and other elective procedures carry extended wait times. Many patients are turned away — not because they lack clinical need, but because they do not rank high enough in priority assessments. Additionally, workforce shortages continue to intensify these pressures. Citizens who cannot afford private treatment increasingly face unmet healthcare needs, with serious consequences for their quality of life.

Consequently, current government policy has turned its attention to the private sector as a potential solution.

The Growing Role of Private Healthcare in New Zealand

New Zealand has always operated a mixed healthcare delivery model. General practitioners function largely as private providers, subsidised by the government. Parallel public and private hospitals serve different patient populations. However, recent policy discussions signal a meaningful shift — one that would accelerate private sector participation well beyond the existing baseline.

Current government efforts to reduce public waiting lists focus on routing more patients through private service providers. This approach has drawn both support and scrutiny. Supporters argue that private investment can fill gaps left by an overstretched public system. Critics, meanwhile, point out that the government has yet to articulate a comprehensive framework for how this shift will work in practice.

What the Westpac Report Recommends

A recent report by Westpac bank has brought the conversation into sharper focus. The report documents the growth of the private sector in New Zealand’s health system and outlines the government’s support for that trend. Furthermore, it frames private funding and service provision as not only valuable but essential — both for solving healthcare challenges and for generating investor opportunities.

Westpac specifically recommends a public-private partnership (PPP) model. Under this approach, the private sector would invest in physical infrastructure such as hospitals and clinics, as well as IT systems and digital health services. The report positions this as a win-win scenario. However, before any partnership model moves forward, several fundamental questions deserve serious attention.

Key Questions That Must Be Answered First

New Zealand operates within a capitalist economy. Therefore, the private sector will always play some role in healthcare delivery. The real issue is not whether the private sector participates — it already does. The real issue is how that participation is structured, governed, and held accountable.

Several critical questions remain unanswered:

• Who bears the risk when private providers fail?
• How will equity of access be guaranteed for all citizens?
• What accountability measures will apply to private partners?
• Which policy levers will the government use to manage performance?
• What outcomes does the government actually expect from this arrangement?

Without clear answers, New Zealand risks expanding private sector involvement without the safeguards needed to protect patients or the public purse.

Lessons From Global Public-Private Healthcare Models

Other countries offer instructive examples. Australia, for instance, operates a broadly similar mixed-delivery system. However, Australia performs less well on equitable access to care. Moreover, a large for-profit private hospital group collapsed in 2025, forcing the public sector to intervene. This outcome demonstrates that private healthcare infrastructure is not inherently stable or self-sustaining.

Beyond Australia, systems ranging from the United States to Singapore each reflect different public-private balances — and each carries its own challenges around access and equity. These international examples confirm one important lesson: the architecture of a mixed system matters enormously. Without deliberate design, it can entrench inequality rather than reduce it.

The Risk of Market Failure in Private Healthcare

When private infrastructure grows faster than public capacity, governments face a heightened risk of market failure. Technology businesses, in particular, have a poor track record when it comes to delivering on large-scale healthcare projects. In New Zealand, the SWIFT project at the former Counties Manukau district health board stands as a prominent example of large-scale IT failure. More recently, a data breach at Manage My Health raised serious concerns about security in digital health services.

These examples are not anomalies. They reflect a pattern. Therefore, the government must approach private sector expansion with clear oversight mechanisms already in place — not as an afterthought.

Workforce and Capacity Concerns

One of the most overlooked risks in accelerating private healthcare expansion is the effect on the public workforce. As the private sector grows, it draws specialists away from public hospitals. Private practice is more financially rewarding. Unless the government actively recruits more specialists and maintains competitive conditions in the public system, the public healthcare workforce will gradually erode.

Political leaders must be transparent about how they plan to maintain this balance. Expanding private capacity while hollowing out public services is not a healthcare strategy — it is a slow transfer of risk onto the patients who can least afford private care.

Funding and Equity Cannot Be Afterthoughts

If public-private partnerships are to deliver equitable outcomes, every citizen must have equal access to essential services. This requirement demands clarity on funding models. New Zealand has several options to consider. One possibility involves extending the Accident Compensation Corporation scheme to cover a broader range of healthcare. Another involves adopting a model similar to Australia’s Medicare or Japan’s comprehensive insurance funds.

Each option involves trade-offs. However, the common requirement across all of them is transparency. The government must state clearly what it values, what it intends to achieve, and how it will measure success.

New Zealand Needs a Clear Direction

New Zealand can draw from a wide range of international examples to ensure a public-private mix delivers on its promise. The models exist. The evidence is available. What is currently missing is a clear statement of intent from political leaders.

So far, no such plan has emerged. Without one, expanded private sector involvement in healthcare carries significant risks — for equity, for workforce sustainability, and for public trust. The government must move beyond endorsing the trend and begin defining the terms on which it will proceed.
