Auckland’s new mayor Wayne Brown has announced a campaign to eradicate mobile black spots across the city, RNZ reports, but a telecommunications expert says the move isn’t financially viable. “Mobile coverage is vital for road safety, emergency services, civil defence and the wider functioning of commerce in our region,” said Brown. “Aucklanders are right to be frustrated when mobile coverage in the city is substandard and limited. It is time to fix the remaining black spots in Auckland’s mobile network,” he added.
