Adidas was "in a very difficult position" as it could not openly criticise its retailers or release commercially sensitive information, Mr Tew said.
Meanwhile, sales of the replica jerseys have leapt following the price cut.
Rebel Sport owner Rod Duke today said there had been a noticeable increase in sales.
"They've gone particularly well, we announced it (the price drop) at 11 o'clock yesterday and through all Rebel Sport stores trading is very brisk."
The retailer knocked $50 off the price of the rugby World Cup replica All Blacks jersey, taking it to $170, while the standard All Blacks replica jersey was $30 cheaper at $149.50.
The row was sparked after the two shirts were listed on the www.worldrugbyshop.com website at US$89.99 ($110) and US$79.99 ($97.85) respectively, plus shipping.
Stirling Sports and Champions of the World matched the price cut, but Champions of the World managing director Gary Marshall said they would not be making a profit on the jerseys.
Mr Duke yesterday said he was upset adidas had refused to reduce its price.
"We happen to believe that this jersey belongs to the New Zealand public," he said.
"They don't own it. We all do. We cannot have a situation where New Zealanders would pay more for All Black jerseys than almost any other country in the world."
