New Zealand Landslides: Missing Persons & Live Updates
- Recovery efforts for communities devastated by Cyclone Gabrielle in February 2023 are facing renewed challenges as recent landslides continue to destabilize land and disrupt infrastructure.
- Heavy rainfall in late December 2023 and January 2024 triggered a surge in landslide activity across areas already weakened by Gabrielle's impact.
- The landslides are causing meaningful damage to roads, bridges, and utilities, hindering access for emergency services and delaying reconstruction work.

Recovery efforts for communities devastated by Cyclone Gabrielle in February 2023 are facing renewed challenges as recent landslides continue to destabilize land and disrupt infrastructure. the damage is particularly acute in the Hawke’s Bay and Tairāwhiti regions of New Zealand.
Ongoing Landslide Activity
Heavy rainfall in late December 2023 and January 2024 triggered a surge in landslide activity across areas already weakened by Gabrielle’s impact. According to a report released by the GNS Science on January 18, 2024, over 300 new landslides were detected in the week following the rainfall, bringing the total number of landslides since Cyclone Gabrielle to over 3,500. This represents a 25% increase in landslide counts as the initial event.
Impact on Infrastructure and Communities
The landslides are causing meaningful damage to roads, bridges, and utilities, hindering access for emergency services and delaying reconstruction work. State Highway 5, a critical transport route through the eastern Bay of Plenty, remains partially closed due to multiple slips. As of January 22, 2024, NZTA (New Zealand Transport Agency) reports 15 road closures across the affected regions due to landslides and flooding.
Financial Costs and Government Response
the economic impact of the ongoing landslides is ample. the initial cost of cyclone Gabrielle damage was estimated at NZD $13.5 billion (approximately USD $8.3 billion as of January 22, 2024) by the New Zealand Treasury. The additional landslide damage is expected to increase this figure significantly. The New Zealand government has allocated an additional NZD $50 million (approximately USD $31 million) in funding for landslide recovery and stabilization efforts, announced on January 15, 2024, by Minister for Emergency Management, Kieran McAnulty.
Long-Term Recovery Concerns
Experts warn that the risk of landslides will remain elevated for years to come, particularly during periods of heavy rainfall. A study published in the Nature Geoscience journal on December 1,2023,indicated that the saturation of hillsides following cyclone Gabrielle has significantly increased the susceptibility to future slope failures. This poses a long-term threat to the viability of some communities and raises questions about the feasibility of rebuilding in the most vulnerable areas.
