nib group’s long-serving technology leader, Brendan Mills (pictured), has left the health insurer after more than two decades with the group, prompting an interim reshuffle of its technology function across Australia and New Zealand.
Mills, who finished at nib in January 2026, served as group chief information officer for about 13.5 years, following earlier roles including group IT manager and IT infrastructure services and operations manager. According to his professional profile, he was responsible for enterprise technology, data, and AI initiatives supporting nib’s health, travel, life, and National Disability Insurance Scheme-related businesses. “As group CIO, I led enterprise technology, data, and AI-enabled transformation at nib, ensuring capabilities drove growth, operational performance, and member value,” he wrote on LinkedIn.
Mills said he “shaped and delivered a multi-year transformation agenda, modernising core platforms; embedding enterprise-wide AI, cloud, and automation capabilities; and positioning technology as a strategic enabler of corporate strategy.” His profile also refers to a nine-year cloud program that ended with the closure of nib’s final physical data centre in 2024, and work to treat data as a strategic asset for personalisation and business impact. During his time in the role, nib introduced machine learning to support claims processing and deployed a chatbot service branded “nibby.” These moves form part of the sector-wide shift toward digital self-service and data-driven decision-making in health and general insurance.
IT News reported that following Mills’ exit, nib has appointed internal executive Glenn Moore as acting group chief technology and transformation officer. Moore has been with the group for more than 13 years and is head of experience, transformation, and productivity. According to nib’s corporate profile, Moore is “responsible for driving the organisation’s technology strategy and transformation agenda [and] leads initiatives that enhance digital capability, optimised systems and delivery of innovative solutions.” The profile also notes his experience in technology leadership and business transformation with a focus on digital health and insurance services. The interim arrangement places day-to-day responsibility for technology strategy, delivery, and platform change with an established internal leader while the group continues to invest in AI, cloud-based infrastructure, and data platforms across its health and National Disability Insurance Scheme-related operations.
The leadership change follows nib’s Dec. 19, 2025, announcement outlining non-recurring items expected to affect statutory operating profit for the first half of FY26, while leaving underlying operating profit unchanged. nib said non-recurring cash expenses in 1H26 are expected to be about A$17 million. This compares with A$21.5 million in FY25 one-off and non-recurring expenses, including M&A and integration costs, and is higher than the 1H26 level indicated at the FY25 results briefing. The group said the 1H26 total includes a net cash expense of about A$8 million (before tax) from historical adjustments to the Private Health Insurance Australian Government Rebate (AGR) and the New South Wales Hospital Insurance Levy (HIL). It expects the combined AGR/HIL impact to be around A$10 million across FY26, with roughly A$2 million of that in the second half.
In New Zealand, nib has also altered its legal and operating structure. On June 30, 2025, nib NZ completed the amalgamation of its two operating entities – nib nz limited and nib nz insurance limited – into a single company now operating as nib nz limited. The move brings health, life, and living insurance operations under one licensed entity. The company said combining the businesses was designed to change how members deal with the insurer, without altering coverage. Members whose policies were previously issued by nib nz insurance limited will now see nib nz limited as the insurer, while existing nib nz limited policyholders are unaffected.
