It's a Fact...
KAIKOURA LOOKS ON
When Captain James Cook encountered the Kaikoura peninsula he named it "Lookers On" because of his experience with the local Maori. During his circum-navigation of New Zealand in 1770, Cook passed Cape Campbell, sailing south to investigate what lay beyond. On 15 February, his ship was approached by four canoes, in which were 57 Maori. However, they would not talk or trade and returned to land from where they followed the ship's progress south.
