Auckland shopping space could expand by 70,000sq m annually in the next two decades, equivalent to about 10 football fields a year.
Floorspace will grow from 1.84 million sq m to 2.46 million sq m by 2021, according to a detailed analysis by Adam Thompson, of Development Economics, who identified Auckland International Airport, Silverdale, Westgate, Flat Bush and Newmarket as ripe for more new shops.
Plans were not in place for buildings to rise on specific sites in all these areas, he indicated, but talk in the market showed growth was most likely in those regions.
However, the new centres will not undermine existing strongholds like the CBD, Newmarket, Glenfield, Sylvia Park, St Lukes, Albany and Botany.
"The modelled impact of new retail projects in the developments pipeline indicates that the primacy of these centres will not be challenged," Thompson found.
