Off the beaten track with Kennedy Warne

Today is Columbus Day in the Americas, or Leif Erikson Day, if you prefer, or Indigenous Peoples Day or Native American Day - the variety of names indicative of the vexations inherent in commemorating the past. Kennedy Warne talks to Kathryn Ryan about whose past is being celebrated. Also, in a couple weeks New Zealand's newest commemoration will be held, the Raa Maumahara National Day of Commemoration, remembering the New Zealand wars.
