Mr Gray, whose development company was separately placed in voluntary liquidation in October last year, was called before the court yesterday by Judge Osborne, but he was not present during the brief hearing.
Between 2000 and mid-2007, Mr Gray was involved in marketing six apartment complexes in Dunedin, a total of almost 50 apartments.
In April 2007, his latest project reported at the time was a joint venture project of a 1900s-era building in Manse St.
Mr Gray could not be contacted yesterday.
Legal counsel for Diners Club said after the hearing the debt owed was about $20,000 on the charge card.
Mr Gray's Manse St apartment development was reported in early-2007 to have cost more than $2.5 million, including $400,000 on earthquake-proofing, with the seven apartments priced between $348,000 and $640,000.
Mr Gray's company, Multimarketing Developments Ltd, was placed in voluntary liquidation in mid-October last year, with the liquidator's first report saying at the time that "a dispute arose as to payments due for the development that could not be be resolved" and, as director, Mr Gray "took the responsible steps" to put the company in liquidation.
A liquidator's report by Insolvency Management Ltd for the six months to April this year showed most of the debt of Multimarketing Developments amounted to $290,000 owed to unsecured creditors.
The company traded from a building in Carroll St in Dunedin and this had since been sold for about $400,000.
However, the liquidators said this left a shortfall to a building society which had a loan against the building.
Iain Nellies, of Insolvency Management Ltd, said yesterday "other matters" were still being resolved and depending on the outcome there was a possibility of some form of payment to the unsecured creditors.
