UniMed has announced that chief executive Louise Zacest will step down at the end of March, marking a leadership transition as the company strengthens its position as New Zealand’s third-largest health insurer.
Board chair Peter Tynan acknowledged Zacest’s role in UniMed’s expansion, highlighting key developments that have taken place under her leadership.
“Under her guidance, UniMed has become New Zealand’s third largest health insurer, expanded into health & safety and mental wellbeing, and significantly strengthened its internal capabilities,” he said.
Zacest expressed confidence in UniMed’s ability to maintain its momentum and continue building on recent achievements.
“It has been an incredible journey leading UniMed through this period of growth and transformation,” she said. “I am immensely proud of what we have achieved together and confident that the company will continue to thrive under new leadership.”
During her tenure, UniMed expanded its market presence, including the recent transfer of Accuro Health Insurance’s portfolio. The transfer, which was finalised on May 31, 2024, following approval from the Reserve Bank of New Zealand (RBNZ) in April 2024, increased UniMed’s membership and reinforced its financial position.
To manage operations during the transition, UniMed has appointed Lynne Hayman (pictured) as interim CEO from March 31 to Oct. 31.
Hayman joined UniMed in late 2023 as interim chief operating officer and has previously held executive leadership roles across multiple industries. Her experience includes serving as chief executive of the Royal New Zealand College of General Practitioners.
Tynan said Hayman’s leadership would ensure continuity as the organisation continues its growth trajectory.
UniMed, officially known as Union Medical Benefits Society Ltd, now provides health insurance coverage to more than 140,000 members across New Zealand. The integration of Accuro’s portfolio represents a key part of the insurer’s broader strategy to expand its reach in the country’s private healthcare sector.
