Post your news and requests for information in the forums, which has topics for finding whanau (family), whanau events (tangihanga, funerals, reunions, anniversaries etc), general korero as well as events.
There is also a calendar which you can add your events to and a link section where you can add your Maori sites.
I belong to www.myheritage.org which is a free site & have printed a few charts for whanau & friends. Coloured & laminated with photos, dates, places etc., mine are 6 feet wide, beautiful taonga. You can find photos, dates etc. on there if someone else shares some of your tipuna, a green icon comes up saying Smart Match. Then you can review the match, compare & edit yours directly from theirs.
