RAINBOW'S FOOTPRINT
Tapuae-o-Uenuku is the highest peak in the northeast of the South Island. The name translates from Maori as "footprint of the rainbow". At 2,880 metres it dominates the Inland Kaikoura Range, rising high above the valleys of the Clarence and Awatere Rivers. The first European to sight the mountain was the explorer James Cook, who called it Mount Odin, but later nicknamed it "The Watcher" since his ship seemed to be visible from it at so many points along the coast.
