New Zealand's North Island Grapples with Dual Severe Weather Disasters

New Zealand's North Island has been hit by two distinct periods of severe weather, beginning in January and continuing into February, resulting in multiple fatalities, widespread infrastructure damage, and ongoing recovery efforts across the island.

A devastating landslide at a campsite in Mount Maunganui in January led to the presumed deaths of six individuals. This was followed by a subsequent low-pressure system in February, which caused an additional fatality and widespread disruptions. These events have prompted multiple emergency declarations and significant challenges for communities.

January Severe Weather Event and Mount Maunganui Landslide

On a Thursday in January, a tragic landslide occurred at the Beachside Holiday Park campsite, nestled at the base of Mount Maunganui. This site is located approximately 230 kilometers southeast of Auckland on New Zealand's North Island. The incident, which happened around 9:30 AM local time, followed days of heavy rainfall in the region.

Tauranga, near Mount Maunganui, recorded an extraordinary 274 millimeters of rain within 24 hours – an amount equivalent to three months' worth of rain in a single day, surpassing a 1910 record. The landslide caused extensive damage, impacting campervans, cars, tents, and an ablution block at the holiday park. Initial reports immediately indicated several people were missing.

Rescue operations, spearheaded by urban search and rescue teams equipped with sniffer dogs, initially aimed to find survivors. However, on Saturday, these efforts transitioned to a recovery operation after human remains were discovered on Friday evening.

Police Superintendent Tim Anderson confirmed that the expectation of finding survivors had ceased, citing the unstable ground conditions and complex environment. Six individuals are presumed to have died as a result of the landslide.

New Zealand Police subsequently released their names:

• Lisa Anne Maclennan, 50, from Morrinsville (a literacy tutor)
• Måns Loke Bernhardsson, 20, from Sweden
• Jacqualine Suzanne Wheeler, 71, from Rotorua
• Susan Doreen Knowles, 71, from Ngongotaha
• Sharon Maccanico, 15, from Auckland
• Max Furse-Kee, 15, from Auckland

Recovery efforts remain ongoing, with bodies being transported to mortuaries in Hamilton and Wellington for identification. Chief Coroner Judge Anna Tutton stated that the identification process could be prolonged. Families of the victims have issued statements through the police.

"Six individuals are presumed to have died as a result of the landslide at the Beachside Holiday Park campsite, following an unprecedented 274 millimeters of rain within 24 hours."

Reports indicate that minor slips occurred on the mountain before the main, catastrophic landslide. Crucially, a local resident contacted emergency services at 5:47 AM, nearly four hours before the major landslide, to report an issue. Emergency services notified the Tauranga City Council, the landowner of the affected site, at 5:51 AM. One of the presumed victims, Lisa Maclennan, had reportedly warned other campers about observed slips and recommended moving to a safer location.

Prime Minister Christopher Luxon visited the disaster site and subsequently called for an independent inquiry into the events. He cited pressing questions about potential earlier evacuation opportunities and a possible "inherent conflict" between the council and its owned campground. The Tauranga City Council has also initiated its own investigation into the tragedy. In a gesture of respect and spiritual protection, an Iwi (local Māori tribe) has declared a rahui, a traditional prohibition, preventing access to the mountain, which is considered a sacred Māori site.

The January severe weather system extended its reach far beyond Mount Maunganui, causing widespread flooding and additional landslides across significant portions of New Zealand's North Island. States of emergency were declared in the Bay of Plenty, Northland, Coromandel, Tairāwhiti, and Hauraki regions due to the severity of the conditions.

Additional fatalities reported during this period include:

• Welcome Bay/Tauranga: Two individuals, a grandmother and her grandchild, died in a separate landslide that destroyed a residence. One of the deceased was confirmed as a Chinese national. Another individual at this scene sustained serious injuries.
• Mahurangi River (north of Auckland): A 47-year-old man was tragically swept away in the Mahurangi River after his car fell into the water. He had reportedly pushed his nephew to safety. His body was later recovered.
• Papamoa: Two fatalities resulted from a separate landslide in this area.

Approximately 8,000 residents were initially left without power across the North Island. Evacuations were ordered for the Mount Maunganui campsite and a surf club in another part of Mount Maunganui due to concerns about further landslide risks.

Subsequent February Severe Weather Events

In early February, a new low-pressure system brought another wave of heavy rain and severe gales to large parts of the North Island. MetService, the national weather service, responded by issuing red weather warnings – its highest level – for regions including Manawatū, Rangitīkei, and Ruapehu Districts. These warnings indicated a "threat to life from dangerous river conditions, significant flooding and slips." The most intense weather was projected for late Sunday, with conditions expected to gradually improve on Monday.

MetService issued red weather warnings, its highest level, for multiple districts, indicating a "threat to life from dangerous river conditions, significant flooding and slips" as the new low-pressure system hit.

Tragically, one additional fatality was confirmed during this February storm when a man, identified as Brent Knowles, was found deceased in a submerged vehicle on State Highway 39 in Puketotara.

The storm caused widespread disruptions across various sectors:

• Power Outages: Approximately 18,025 Powerco customers and 6,500 Wellington Electricity customers experienced power loss. Powerco later reported around 6,780 properties on the North Island remained without power.
• Infrastructure and Travel: Numerous roads were closed across the country due to flooding and slips, leading to isolated communities. Flights at Wellington Airport faced cancellations or delays due to high winds, and swells in the Wellington area were projected to reach up to 7 meters.
• Water Supply: Residents in Pirinoa were advised to boil drinking water, and residents in Taihape, Mangaweka, Hunterville, and Rātana were instructed to conserve water due to compromised supplies.
• Evacuations: Approximately 80 individuals were evacuated to an emergency center. Evacuations were also ordered in Onepoto and parts of Te Araroa due to heightened landslide risks.

In response to the escalating conditions, states of emergency were declared in several districts, including Waipā, Ōtorohanga, Manawatū, Rangitīkei, and Tararua. The Wairarapa region bore the brunt of the storm, recording an intense 256.4mm of rainfall and wind gusts reaching a staggering 240km/h. Meteorological services forecast thunderstorms and strong winds to continue in affected regions, potentially hindering ongoing recovery operations from the earlier Mount Maunganui landslide.
