Devonport Naval Base - HMNZ Naval Base - is the home of the Royal New Zealand Navy, located at Devonport on Auckland's North Shore. The base consists of HMNZS PHILOMEL (the administration center for the base), the Fleet Support Organization, and the Fleet Personnel and Training Organization. One of the more famous elements of the base is the Calliope Dock, a drydock built in 1888 and still in use. At that time, it was the largest in the Southern Hemisphere, and a strategic asset for the Royal Navy.
