RNZAF Base Auckland is a Royal New Zealand Air Force base located near the upper reaches of the Waitemata Harbour in Auckland, New Zealand. The base formerly comprised two separate airfields, Whenuapai and Hobsonville. Hobsonville was established as a seaplane station in 1928 and was the RNZAF's primary flying boat base in New Zealand until 1967. Construction of Whenuapai as a base for Wellington bomber aircraft began in 1937, and from 1945-1965 Whenuapai was also Auckland's civil international airport. Post World War II Auckland became a centre for RNZAF transport and maritime squadrons. These two independent bases were integrated in 1965 to form RNZAF Base Auckland. Hobsonville subsequently became a grass airfield for No. 3 Squadron RNZAF which has now moved to Ohakea.
