MAS appoints former ASB CFO and award-winning finance leader Jon Raby to Board

MAS is pleased to announce the appointment of senior financial executive and governance expert Jon Raby to its Board, effective 26 August 2026. 

Jon brings more than 25 years’ experience in executive leadership across major financial services organisations in New Zealand and Australia. His career includes a decade as Chief Financial Officer of ASB Bank, where he led finance, treasury, capital management and risk functions in one of New Zealand’s most complex regulated environments. He has deep experience in financial governance, regulatory engagement, risk oversight and steering organisations through change. 

Jon is widely recognised for his contribution to the financial sector, including being named Deloitte Top 200 New Zealand CFO of the Year in 2018. 

MAS Chair Doug Hill says Jon’s appointment adds valuable capability and perspective to the Board. 

“Jon brings extensive experience from senior roles across banking and financial services, with a strong track record of operating in complex environments and supporting organisations through periods of transformation,” he says. “His depth of experience in financial governance, risk management and strategic leadership will help support MAS’ ongoing focus to invest in the Member experience, while delivering strong financial returns and adding long-term Member value.” 

Jon also holds non-executive and advisory roles, including with the New Zealand Shareholders’ Association and SmartShares, where he chairs the Audit and Risk Committee. His governance experience spans banking, funds management, securities broking, insurance, property management and high-technology manufacturing. 

Jon says joining the MAS Board is a privilege and strongly aligned with his values. 

“MAS stands out for its mutual structure and its long-term commitment to Members. That purpose-led approach is something I strongly support,” he says. “MAS has a disciplined, thoughtful way of balancing Member outcomes with long-term sustainability. It’s an organisation that clearly takes a strategic view of the future, and I’m looking forward to contributing to its ongoing financial strength and resilience.” 

He says MAS’s focus on trusted advice, Member wellbeing and intergenerational value is a defining strength. 

“MAS has a proud history of serving professionals who care for New Zealanders, and it does so with integrity, prudence and a genuine commitment to mutual benefit. Supporting that mission and working with the Board and leadership team to build on it is something I value.” 

At MAS’s Annual General Meeting on 26 August 2026, Members formally approved Jon Raby and Jennifer Lang as Commercial Trustees, and Steve Merchant as Practitioner Trustee.  

The appointments reflect the breadth of experience and expertise across the MAS Board and support a continued focus on strong governance, long-term sustainability and delivering greater value for Members.
