MAS is a membership-based insurance and investment company for New Zealand professionals.

As a mutual society, our customers become Members. We're owned by our Members so we don't have to generate big profits for external shareholders.

Our Members, our priority.

MAS is a member-based organisation for professionals, like you. As a mutual, we’re owned by our Members and we exist to protect your interests, not the interests of external shareholders. We're always looking for ways to put you first, especially during the claims experience.

Life and Income Insurance

Security for you and your family

Planning for the worst can be a difficult conversation, but if you were seriously ill or injured or were to pass away unexpectedly, you'd want to make sure your family can still pay the bills. 

Our insurance solutions can help remove your worry about your family’s financial future if something happens to you. To make things easier, we have commission-free advisers that come to you and are available to talk at a time that’s convenient for you.

We believe in what’s good for business, and know that sometimes our Members need support developing theirs.
