Robt Jones Holdings, which calls itself New Zealand's largest private CBD office building owner, got a High Court judgment in September 2009 against Northern Crest for about $300,000, which was paid after liquidation proceedings were brought.
The now-failed firm then settled other debts with the property mogul's company before moving operations across the Tasman in November 2010.
Northern Crest liquidators hope the dispute over the $750,000 will get to court in the middle of this year.
The tape was a recorded discussion between former Lombard chief executive Michael Reeves and Northern Crest liquidator Steve Lawrence. Reeves has said he advised Northern Crest's directors on corporate governance. The recording emerged during a case where Australian firm Manifest Capital Management had a A$3 million claim admitted into Northern Crest liquidation.
The judge said the tape and transcript were not formally put as evidence before him in the Manifest case. "Whether they ended up on the court file is something I do not know but they should not be there if they did."
