The Emergency Services channels are the main operating channels of choice for responding agencies. Police also have 10 LandSAR channels and the Marine channels are essential for responses within the Marlborough Sounds and in Cook Strait. Marlborough Marine Radio and Coastguard monitor the marine channels 24/7. FENZ, Department of Conservation and CDEM have access to portable repeaters which can be transported to provide coverage to a specific location if required. These can be powered by a portable generator, solar panel or batteries depending on the expected use.
