We're a Kiwi business owned by you

We’re a 100-year-old mutual so when you switch your KiwiSaver account to MAS, you become one of our Members and owners. And our profits help fund the MAS Foundation, not overseas shareholders.

Choose the right fund for you

Investors have different goals, different risk appetites and are at different stages of life. That’s why we offer seven KiwiSaver funds – each with their own risk profile – so you can choose a fund specific for your situation.
