New Zealand health plan costs to surge 18% in 2026, outpacing region

Employee health plan costs in New Zealand are projected to rise by 18 percent in 2026, according to new industry data. This increase is significantly higher than the global average of 9.8 percent and the Asia Pacific regional average of 11.3 percent.

The projections come as New Zealand faces a combination of demographic and systemic pressures on its healthcare system.

Rising costs

The projected 18 percent rise for 2026 continues a trend from the previous year, with 2025 medical plan costs forecast at 17 percent. Analysts point to a combination of an ageing population, growing rates of chronic diseases, increased utilisation of healthcare services, and the adoption of advanced medical technologies as key contributors to the cost escalation.

Cardiovascular conditions, cancer, hypertension, diabetes, and musculoskeletal issues remain the most significant drivers behind rising claims and medical expenses, according to the findings. Delays in the public health system observed between 2023 and 2025 have also contributed to higher demand for medical plans provided by employers.

Regional comparison

The increase in healthcare cost forecasts for New Zealand sharply contrasts with trends elsewhere.

The Asia Pacific region is expected to see a rise of 11.3 percent in 2026, with the global average even lower at 9.8 percent. These figures place New Zealand among countries with the fastest-growing costs for employer-sponsored medical plans.

Industry experts state that while public healthcare offers a wide safety net, increasing demand for supplementary health plan options among the workforce has led employers to seek new approaches to manage expenditures and support employee wellbeing.

Employer response

Organisations are adopting a range of initiatives to tackle the growing burden of healthcare costs. Preventive health and wellbeing programmes, which focus on physical activity, nutrition, mental health, and stress management, are becoming more common. Regular health screenings and vaccination drives are also seen as effective ways to address potential health issues before they become severe and costly.

Support for mental health is a significant aspect of employer strategies. Programmemes include employee assistance offerings, designated mental health days, and workplace training aimed at fostering a positive environment. Digital health and telemedicine services are increasingly used, providing employees with easier access to care and health tracking tools.

Companies are also investing in healthy work environments, such as ergonomic office setups, access to healthier meal choices, and encouragement for movement throughout the working day. A growing emphasis on data-driven insights is enabling employers to identify health trends more accurately and customise interventions for their staff.

Data-driven insights

By leveraging workforce health data, organisations can measure the impact of their initiatives and adjust strategies in response to evolving needs. Trends identified through employee health data allow companies to focus resources more efficiently and prioritise interventions with tangible outcomes for both costs and wellbeing.

"New Zealand's exceptionally high medical trend rate signals a pivotal moment for employers. While universal healthcare provides a strong safety net, the sharp rise in supplementary medical costs highlight the need for a more holistic approach to workforce wellbeing. Employers who invest in preventive health and mental health support are not only managing costs - they're building a healthier, more engaged and resilient workforce ready to meet tomorrow's challenges," said Anson Davies, head of Health Solutions, New Zealand, Aon.
