"Auckland continues to dominate the real estate market in terms of price movements. The strong price movements in Auckland, particularly on the North Shore and in Rodney, continue to be driven by high demand from all types of property buyers and from a lack of sufficient new supply - both new builds and listings of existing properties," Milne says.
