Cyclone Gabrielle, New Zealand, February 2023The Government in New Zealand declared a National State of Emergency in response to Cyclone Gabrielle. The declaration applied to the regions of Northland, Auckland, Tairawhiti (Gisborne), Bay of Plenty, Waikato, Hawke's Bay and Tararua District. Strong winds downed trees and power lines, leaving over 200,000 without electricity. Some areas of the Gisborne region were also without internet and telecommunications. Air New Zealand cancelled hundreds of domestic and international flights. Storm surge, high tides and high waves caused coastal flooding in areas around the east coast and far north of the North Island. Torrential rain triggered floods and landslides across several regions including Hawke's Bay, Gisborne, Northland, Waikato and Auckland. Officials in Gisborne Region said rivers jumped to record levels in several locations. A firefighter is missing after a landslide in Muriwai in West Auckland. Hawke’s Bay Region The Wairoa River burst its banks, affecting around 4,000 people in the town of Wairoa. 8,000 residents isolated. In Central Hawke's Bay District, the Waipawa and Tukituki Rivers both broke their banks. The Ngaruroro River overtopped its banks, resulting in the evacuation of the village of Omahu. Earlier in the day residents in Taradale and parts of Meeanee were evacuated given the level of the Tutaekuri River but were later allowed to return home. Civil Defence said one person remains trapped in a home in Putorino following a landslip. Gisborne Region Tairawhiti (Gisborne) Regional Civil Defence residents in the Ormond township near the Mahunga Stream should evacuate if safe to do so after the rapid rise of the Waipaoa River. Residents in areas near the Waimata river in the city of Gisborne also evacuated their homes after river levels rose. Bay of Plenty Region Coastal floods caused by high tides and storm surge in the Bay of Plenty Region prompted evacuations in Little Waihi near Maketu and Opotiki on 13 February. Waikato Region Areas of the town of Thames were flooded after the Kauaeranga River broke its banks. Northland Region In Northland Region, several residents in central Whangarei were evacuated due to the threat of landslides. Other evacuations were carried out in Dargaville due to the threat of flooding from high tides and high river levels.
