German-born Dotcom, 38, is accused, with three other men, of breaching international copyright laws to the value of US$500 million ($595 million) through Megaupload, the file-sharing site he founded.
Crown prosecutor Anne Toohey yesterday told the court Dotcom was still a flight risk.
She said two bank accounts had been discovered since the last hearing and there was still a risk of Dotcom getting illegal travel documents.
Dotcom's lawyer, Paul Davison QC, said his client would spend 25 weeks in jail if the court reversed the decision.
Mr Davison said his client had no more money available to him and had no intention of going back to Germany.
Justice Tim Brewer will deliver his decision today.
