The Christchurch City Choir has a big Pasifika concert this weekend. The concert begins with a traditional presentation of Karanga and Haka by Te Kotahitanga, the longest running Kapa Haka group in Te Waipounamu. The second half will be a performance of David Hamilton's 'Missa Pacifica'. Te Kotahitanga is led by Tihi Puanaki of Ngāti Hine, who's been working in the Māori community of Christchurch for over forty years. Sue Densem is the solo soprano for this weekend's performance, taking her away from her regular gig, directing the Burnside high senior chorale.
