Next steps for Nelson Tasman weather radar
Nelson Tasman will gain a new weather radar near Drumduan’s Horoirangi Peak by mid-2027, improving severe weather monitoring and disaster preparedness after recent flooding events.
The New Zealand Government has selected a site for a new weather radar in the Nelson Tasman region, marking a key step in enhancing local weather monitoring. Emergency Management and Recovery Minister Mark Mitchell and Associate Transport and South Island Minister James Meager highlighted the project’s urgency following severe weather events in July 2025. The Government fast-tracked the initiative with a commitment of up to $5 million to address gaps in regional radar coverage.
Nelson Tasman currently relies heavily on the Wellington radar, which fails to adequately monitor parts of northwest Tasman. The region has faced multiple high-impact flooding events, including five states of emergency since 2011. The new radar, located near Drumduan’s Horoirangi Peak, will provide comprehensive coverage from its elevated position 15 kilometres northeast of Nelson City and 630 metres above sea level.
The radar is scheduled to be operational by mid-2027 and will feature modern Doppler dual-polarisation technology. This technology improves rainfall estimation accuracy and enhances overall weather monitoring capabilities across the region. MetService confirmed the project remains on track for its mid-2027 completion date.
The Government emphasized the radar’s role in strengthening New Zealand’s resilience to severe weather. Improved short-term forecasting and rainfall mapping will support emergency agencies, councils, first responders, and communities in preparing for and responding to major events. Better weather information is expected to enable more informed decision-making during emergencies.
