"The issues that Mr Jones raised were specific to blackmail, extortion and retrospective payments.
"The issues that were discussed very briefly with Katherine Rich ... were about dominant behaviour [by supermarkets] which is ... the context of a much larger discussion about all sorts of matters in the industry."
The Commerce Commission is now investigating Progressive's alleged market misconduct. The investigation would look at Mr Jones' claims that the company had been blackmailing suppliers into making retrospective payments to keep products on shelves.
The Commerce Committee yesterday agreed to release a letter sent by Progressive's lawyers to MPs. The letter by a legal team at Russell McVeagh asked for details about a Commerce Committee meeting two weeks ago, in which allegations against Progressive were discussed.
Labour's Clayton Cosgrove, the committee's acting chairman, said the letter was "at best menacing and at worst intimidatory" because Progressive could have easily obtained the information without making the request through its lawyers.
He made a motion to invite Progressive executives to appear before the committee because the company had expressed concerns about the issue of natural justice. But National MPs rejected the motion, saying that an appearance would be used for political posturing.
Labour leader David Cunliffe confirmed yesterday that his party would consider stopping the sale of Lotto tickets at supermarket counters. Prime Minister John Key opposed the move, saying it was "a bit nanny state".
