Dark outlook about the weather

Why do TVNZ 1’s weather forecasters have such a concentration on the South Island’s weather? There are only 1.038 million people in the whole of the South Island, but there are 1.548 million people in Auckland and further north. The weather forecasters spend most of the time gibbering about weather in the South Island and only seconds talking about the weather where most of the people live. Roger Harsant (Kamo)
