Workers sewing the adidas All Blacks jerseys are paid less than $100 a week - yet each jersey is sold for a recommended $220 in New Zealand.
The jerseys are made by the Bowker Yee Sing Garment Factory (He Yuan) Co Ltd, in the city of Heyuan in Guangzhou Province. The 14,100sq m factory employs 2400 staff, half of whom sleep in dormitories.
A workers' rights organisation, Students and Scholars Against Corporate Misbehaviour, plans to investigate the factory before it begins producing uniforms for the London Olympics next year.
In the past week adidas has been the target of a public outcry over the price of its All Blacks replica jersey.
Retailers had to dig into their own margins after the original $220 sale price was decried as being too expensive. The jerseys can be bought overseas for half as much.
