By Leigh Tait, NIWA Cyclone Gabrielle significantly impacted the Hawke’s Bay and Tairāwhiti nearshore marine coastal zone, an area of vital social, cultural, aesthetic and economic importance. The focus of this work was to quickly and effectively acquire data to determine the stressors (sediment and woody debris) and their long-lasting impacts on invertebrates and other […]

Largest known record of mapped landslides from a single event

Cyclone Gabrielle was the largest landslide-triggering event on record in Aotearoa. Our response required development of new landslide mapping and modelling approaches in order to collate the landslide data. This novel approach provides stakeholders with a timely and sufficient level of spatial and positional accuracy about landslide occurrence and severity – where landslides could occur, […]

Cyclone Gabrielle was a severe ex-tropical cyclone that occurred in February 2023. It caused severe landsliding in several zones along the east coast of the North Island. As part of the cyclone response, the Ministry for the Environment contracted Manaaki Whenua – Landcare Research to do a rapid assessment of the damage in hill country […]

Cyclone Gabrielle caused severe flooding and damage across parts of the North Island. In the months following the event, Hawke’s Bay Regional Council (HBRC) initiated a project to identify potential contamination of groundwater in three areas of concern that were subject to significant floodwater inundation: the central north-western part of the Heretaunga Plain, Esk Valley […]

By Rowan Sprague, Manaaki Whenua Landcare Research Project summary In mid-February 2023, Cyclone Gabrielle struck the North Island of Aotearoa-New Zealand, causing widespread devastation. As part of the cyclone response, the Ministry of Business, Innovation and Employment (MBIE) contracted Manaaki Whenua – Landcare Research to deliver a high-level integrated assessment of the immediate impacts of […]

By Murray Ford Assessing the erosional impacts of Cyclone Gabrielle across a large swathe of the country has been possible using satellite imagery collected by very-high resolution satellites and in places, aerial photographs. We have used imagery collected by operators of commercial satellites, the likes of which you see on Google maps. We also accessed […]

Project: Rainfall-induced landslide forecasting, rapid assessment and hindcasting Project Leads: Chris Massey and Kerry Leith (GNS Science) Between 12 and 16 February 2023, Cyclone Gabrielle triggered at least 140,000 landslides across the North Island damaging houses, power lines, bridges, roads and creating dams across channels, and sadly, resulting in the death of five people. This […]

Predictive model comparison on a well-documented wildfire event in New Zealand Pigeon Valley Fire 2019

Samuel Aguilar-Arguello, Wayne Schou, Ilze Pretorius The ability to predict and prevent wildfires is important in safeguarding lives and property. In New Zealand, fire authorities use many tools to predict fire behaviour, one of these being the fire simulation software Prometheus. It was designed to provide near real-time operational decision support by predicting fire growth, […]

Serious games helping tackle serious problems

Serious games helping tackle serious problems Example of a serious game

Serious games offer a playful yet powerful way for scientists, engineers, policy makers, and community members to find the best solutions to complex problems. Something seemingly as simple as deciding whether to rebuild a road damaged by coastal erosion requires a multitude of considerations, ranging from who and how many people depend on the road, […]
