The Wellington rain radar is now fully operational after a major upgrade. Optimisation tests have been completed successfully and the new radar is performing well. 

Due to recent poor weather, the painting of the radar tower is not yet complete and will continue throughout June, and possibly into July, resulting in the radar being temporarily offline during periods of settled weather. 

About the upgrade

The new radar provides central New Zealand with enhanced real-time rain observations particularly important during severe weather events. The radar uses the latest dual polarisation technology which allows meteorologists to identify different types of precipitation, be it rain, hail or snow.

The project involved strengthening the tower structure and replacing the 30-year-old radar hardware with new technology. The new radar will provide improved services to the lower North Island and upper South Island communities, aviation, defence, emergency services and maritime safety.  

The Wellington radar upgrade is part of our ongoing investment in the New Zealand weather radar network, funded through the contract with the Ministry of Transport.
