Almost 200 Christchurch businesses have been opened or reopened since January and the population is growing as the Canterbury city continues its recovery from the 2010 and 2011 earthquakes.
University of Canterbury senior marketing lecturer Dr Sussie Morrish said the new and re-established shops, cafes, bars and restaurants created the potential for further economic growth in the city.
New Regent St shops had been refurbished and the iconic precinct had opened in the CBD, creating small clusters with a potential to grow, Dr Morrish said.
Canterbury's population had grown by 1600 people in the last year, she said.
"This is a significant swing from a year earlier when 3100 more people left the region than came in," Dr Morrish said.
