RNZAF Station Seagrove 50th Anniversary

Can you imagine a secret airfield, hidden in plain sight? RNZAF Station Seagrove, right here in Auckland, was just that. During World War II, as the threat of Japanese invasion loomed, this vital airbase was built covertly on commandeered farmland. The year was 1942. The Clark family, whose “Seagrove” homestead graced the land, unwittingly lent their name to this top-secret operation. RNZAF Station Seagrove became a hidden guardian, protecting Auckland from above. So clandestine was its existence that even airmen from nearby Ardmore aerodrome were baffled by the sudden appearance and disappearance of fighter planes. By 1943, RNZAF Station Seagrove served as a crucial support base for the larger airfields at Mangere and Ardmore. Here, P-40 Kittyhawk fighters and Douglas SBD dive bombers were assembled and deployed. Two 5000-foot cinder runways, intersecting in a boomerang shape, accommodated these powerful aircraft. The base also housed temporary barracks, dug-in revetments, and essential maintenance facilities. All of this was shrouded in secrecy. After the war ended in 1945, RNZAF Station Seagrove’s existence was finally revealed. The base was closed, briefly serving as a surplus aircraft dump before being returned to the Clark family in the 1950s. Although Auckland International Airport was considered for this location, it was ultimately ruled out. The runways then became a playground for speedway enthusiasts. Drag races and speed trials echoed across the former airfield until the surfaces deteriorated. A plaque now marks the site of RNZAF Station Seagrove, a silent testament to its crucial role in wartime history. The runway layout is still visible from the air, a ghostly reminder of this once-secret base. Even today, many locals remain unaware of the vital role RNZAF Station Seagrove played during World War II.
