Overview of our Monthly Meetings
The two hour meeting is held on the first Tuesday morning of each month in Browns Bay. An invited speaker, expert in the field, informs, educates and entertains us. Our focus is Exceptional New Zealanders doing Exceptional Things in New Zealand. A wide range of current topics is covered and we are sometimes privy to information not yet released by the researchers to the public.

The second part of the meeting is provided by our U3A Special Interest Groups whose presentations have been identified as being of interest for the whole membership. A tea break provides the opportunity for members to mix and chat. Attendance at the main monthly meetings is optional. Members are required to attend one or more Special Interest Groups as this is where the active learning focus of the U3A philosophy occurs and long last friendships are made.
