Pleiades appearance brings on Matariki celebrations in NZ

From this week the star cluster Pleiades known in Aotearoa as Matariki will become visible in the sky. Recognition of Matariki has grown considerably in popular culture here in New Zealand over the past few decades - with people all around the country becoming more aware of the celebrations than in the past. Joining me now is perhaps Aotearoa's foremost expert on Matariki - Dr Rangi Matamua, from the University of Waikato.
