To celebrate International Day of the World"s Indigenous Peoples, we"re on New Zealand"s North Island, looking at the Ngatoroirangi rock carving by Māori artist Matahi Whakataka-Brightwell in Mine Bay. This artwork is part of a larger collection of carvings on the edge of Lake Taupo and has become a big tourist attraction despite being accessible only by boat. Four years in the making, the work is a tribute to Māori ancestors and guardians, and the integral roles they play in the Indigenous Māori culture.
