Site selected for new Nelson Tasman weather radar

Nelson Tasman communities are one step closer to more timely and accurate weather information, with a site having been selected for the region’s new weather radar - as announced today by Emergency Management and Recovery Minister Mark Mitchell and Associate Transport and South Island Minister James Meager.

Located about 15 kilometres northeast of Nelson City near Drumduan’s Horoirangi Peak at 630 metres above sea level, the site on private land, provides an ideal position for monitoring weather across the region.  From there you can see all of the catchments around Tasman Bay, over into the Marlborough Sounds and D'Urville Island, and northwest to Golden Bay and beyond.

Identifying the right location for a weather radar is a complex process and takes time to get right.  Over the past year, MetService has assessed a range of potential sites across the region, considering technical, operational and environmental requirements.  As well as engaging with local councils, iwi, landowners and engineers.

Kevin Alder, MetService’s GM Meteorolgical Observing Systems joined Minister Meager, Nelson Mayor Hon Dr Nick Smith, Mayor of the Tasman District Tim King, Ngati Tama Rangatira Anaru Stephens in speaking with media at the announcement event on the banks of the Maitai River - central Nelson - a poignant location given the river flooded during the severe weather event of August 2022.

Kevin says, “We’re aiming to have the new radar operational by mid-2027 – when the detailed information it provides will improve short-term forecasting and rainfall mapping - helping emergency management agencies, councils, first responders and communities better prepare and respond to severe weather events.

“We would also like to thank the site owners for their commitment and support of the project. And we look forward to building strong relationships with local iwi, hapū and whānau.

“The Government’s investment in this radar not only is an investment in the region but also in strengthening the national radar network operated by MetService.  Upon completion this radar will be the 11th in our network – providing a clearer picture of incoming rain and ultimately helping to enhancing New Zealand’s weather resilience.”
