Whangaruru is a locality and harbour on the east coast of Northland, New Zealand. Whangarei is to the south and the Bay of Islands to the northwest. The area was reputedly named by Puhimoanariki , the captain of the legendary waka Mataatua, after searching for a long time he found shelter from bad weather there.
