New Zealand Rugby says leaked "minutes" claiming they agreed to the Rugby Championship schedule were just notes and they always opposed a draw that would see the All Blacks spend Christmas in quarantine.
NZR chairman Brent Impey on Thursday disputed a report claiming there were minutes of a SANZAAR meeting that showed the Kiwis agreeing to the six-week tournament.
Playing the last match on December 12 means the All Blacks, who have to spend 14 days in managed isolation on their return home, will still be in quarantine on Christmas Day.
NZR believed it had an agreement with Australia and SANZAAR that the All Blacks would play six Tests over five weeks, with their last match on December 5.
Impey, who is also the chair of SANZAAR, said there hadn't been a board meeting since August 4. He said there were also many emails that proved an impasse.
"The notes that have been published are not board minutes and they've got a fundamental error in it as far as we're concerned which says the six-week draw was agreed by all," Impey said.
"I can tell you that it wasn't.
"We know that and Rugby Australia and SANZAAR know that because we kept telling them right up until the time they announced the draw."
A source, however, said the printed minutes were from a meeting of SANZAAR chief executives, not the board, and Impey wasn't present with only Mark Robinson representing NZR.
Rugby Australia chairman Hamish McLennan said this week the relationship with New Zealand was at its "lowest ebb" after a recent series of disagreements.
However, Impey said he regarded it as "banter" between the trans-Tasman neighbours.
"The relationship isn't bad at all - we've had a couple of zoom meetings which have been positive.
"It's in our mutual interest to work together."
But Impey would still push for a solution to the scheduling.
"Mark is dealing with that on an hourly, daily basis and there are a number of solutions, and we haven't got one at the moment but it's top of mind."
