NZ SeaRise

NZ SeaRise operates as a digital platform providing location-specific sea-level rise projections for New Zealand, integrating vertical land movement data to generate coastal flood risk assessments. Its core service involves delivering updated scientific projections that inform infrastructure planning, emissions policy discussions, and individual property research. The platform serves a dual audience of local government officials responsible for climate adaptation strategies and residents seeking to understand potential impacts on their homes and communities. By incorporating geological factors like land subsidence, the service offers a nuanced view of flooding timelines, indicating accelerated thresholds for populated coastal regions. This specialization in combining sea-level rise with local vertical land movement data distinguishes its analytical approach within the climate adaptation information space. The website's launch represented a significant step in making complex geospatial climate data publicly accessible for practical decision-making. Its function is explicitly tied to supporting evidence-based responses to coastal hazards, positioning it as a critical resource for both public sector planning and civic awareness. The service emerged to address a clear need for localized, scientifically rigorous data in a country with extensive populated coastlines subject to varying rates of land movement.

The platform's operational context was dramatically highlighted by a cyber attack shortly after its launch on 2 May 2022. The incident involved a denial-of-service assault originating from suspected overseas IP addresses, generating approximately 10,000 hits per second and rendering the website inaccessible. This disruption occurred during a period of heightened interest in its projections, directly impeding access for local officials and residents at a crucial time for climate adaptation planning. Project co-leaders suggested the attack could be linked to actors opposed to climate change messaging or automated bots, though no definitive attribution was confirmed. The event underscored the vulnerability of climate science dissemination tools in contested public discourse and the tangible consequences of service interruption for communities relying on the data. The attack targeted a resource designed to translate complex scientific models into actionable local intelligence, emphasizing its perceived importance and the contentious nature of climate information. This security challenge became an integral part of its early operational history, illustrating the external pressures faced by platforms communicating climate risks. The incident did not alter the platform's stated purpose but served as a stark example of the obstacles in providing authoritative climate data to the public.
