Based on a 2013 census, the amount of retail workers in Auckland surpasses any other city by a long shot.
Auckland's retail workers number 60,000, with Christchurch and Wellington the next most populated. Christchurch has almost 20,000, while Wellington has under 10,000.
Hamilton, Dunedin, Tauranga, Lower Hutt and Palmerston North follow.
The areas of New Zealand employing the least amount of people in the retail trade aren't a surprise - the Chatham Islands leads the way, followed by Mackenzie, Kawerau, Kaikoura and Wairoa.
A separate study by Statistics NZ and Infometrics in partnership with Service IQ found 259,000 people were employed in New Zealand's retail sector in 2012. This was down from a peak of 267,000 in 2008, before the Global Financial Crisis.
Auckland was also found to be the region with the highest number of employees, accounting for 34 percent of retail employees in 2012.

It found women dominate the sector, accounting for almost 54 percent of workers. People of Asian descent were considerably better represented than in the national economy, making up 15 percent of the workforce.
Maori and Pasifika people were found to be under-represented in the industry, making up 10 percent and 4.7 percent respectively.
The report predicted retail sector employment would rise to more than 275,000 people by 2017.
