Much of the property police seized was old and broken, said Mr Niven, and his client repaired and sold it for income.
In opposing bail, the police alleged the couple were supplying methamphetamine in exchange for stolen goods.
More than 100 cellphones, 30 laptops, cameras, iPods and jewellery were found in the apartment.
Judge Anne Kiernan said Clark had failed to satisfy her that bail was appropriate.
While only a small amount of methamphetamine was found, she said the police had found the "trappings of a drug dealer" including a handwritten "tick list" ledger of customers, as well as scales and snaplock bags.
She noted the police submission that "stolen property was often used as currency for drugs" and the serious allegation that Clark was committing crime to supplement his lifestyle as a sickness beneficiary.
The couple will reappear in the Auckland District Court on October 5.
Detective Sergeant Phil Cox, of the Tactical Crime Unit, said his team was now sorting and photographing all the items seized from the apartment in a bid to find the owners.
The police had identified a further 25 offences, ranging from theft to burglary, linked to the property dating back to 2009.
Mr Cox said reuniting property with the rightful owners was hard work but police had already returned one family heirloom to an Auckland woman.
Many of the cameras and phones contained photographs which he hoped people would recognise.
