Severe Tropical Cyclone Gabrielle was the worst tropical cyclone to hit New Zealand since Cyclone Giselle in 1968, surpassing Cyclone Bola in 1988. It is also the costliest tropical cyclone on record in the Southern Hemisphere, with damages estimated to be at least $13 billion NZD. The fifth named storm of the 2022–23 Australian region cyclone season, and the first severe tropical cyclone of the 2022–23 South Pacific cyclone season. Gabrielle was first noted as a developing tropical low on 6 February 2023, while it was located to the south of the Solomon Islands before it was classified as a tropical cyclone and named Gabrielle by the Bureau of Meteorology. The system peaked as a Category 3 severe tropical cyclone, before moving into the South Pacific basin, then rapidly degenerated into a subtropical low on 11 February 2023.
