North Shore, New Zealand

With a population of 205,605, North Shore is a sprawling suburban hub that offers a seaside lifestyle, but at a steep price. The area has rapidly developed since the 1959 construction of the Auckland Harbour Bridge, and now boasts over 22,000 businesses contributing 6% of New Zealand's GDP. However, the bureaucratic headaches of amalgamating five former local authorities into a single "super city" in 2010 persist as a constant source of friction. While the stunning volcanic landscapes and access to outdoor recreation make North Shore appealing, the high cost of living and heavy traffic congestion may deter those seeking a more affordable, slower-paced existence.
