The NZ fire service have no digital networks curently. They have only agreed to go to p-25 digital radio in time. Probbly when they next overhaul there radio system. At the moment they use vhf frequncies for dispatching (uhf in Auckland) and seperate simplex vhf channels for there "incident ground channels" which they use on scene to communicate with each other.
Portables are all moving to UHF with the new UHF radios all being P25 capable Simoco's.
