Supporting you

Engineering New Zealand members and their whānau are warmly welcomed to join MAS. You’ll have access to premium insurance and investment solutions, a nationwide advisory team, wellbeing resources, and the confidence of being part of a mutual that exists solely to benefit its Members.

MAS: Insurance and investment provider for professionals

MAS is a New Zealand-owned mutual insurance and investment provider, established in 1921. We were founded by doctors to take care of their community, and more than a century later we’re proud to serve professionals across Aotearoa New Zealand, including engineers, dentists, lawyers, veterinarians and their families.

We’re different to many other providers because we’re a mutual. That means we’re owned by our Members and have no external shareholders. Every dollar we make is reinvested to strengthen our financial reserves, support our MAS Foundation, improve our products, and expand the services we provide. When you join MAS, you’re in safe hands.

Supporting engineers to thrive

Engineering is a profession that helps shape the future of Aotearoa New Zealand, and our partnership with Engineering New Zealand recognises the role engineers play in building safe, sustainable communities. We want to do our bit by providing access to expert financial advice and quality insurance and investment solutions.

All MAS Members have access to our nationwide team of MAS Advisers at no additional cost. Plus, Members get free access to the Āki Wellbeing Hub, a digital platform supporting physical, mental, financial and nutritional wellbeing. We also offer 3 free Employee Assistance Programme (EAP) sessions for Members each year.

Recognition you can trust

Our commitment to providing outstanding products and service has been recognised with multiple national awards. Our exceptional service and claims experience have led our Members to vote us Consumer People's Choice 9 years in a row for our House, Contents and Car insurance. We've also been awarded Canstar's Most Satisfied Customers awards for Home and Contents Insurance, Car Insurance and Seniors Insurance, and been named 'Favourite Member-Focused KiwiSaver Scheme' in MoneyHub’s 2025 Editor’s Choice Awards. We were praised for our outsourced investment approach, Member-first ethos and unique mutual model.

These honours reinforce our trusted service, value and care for our Members.
