The Crown claims that the sick child was fictitious and made up to "engender trust and sympathy".
But Wright says she had nothing to do with the fake trades – and blames former husband Paul James Bennett who last month was jailed for more than three years after admitting a series of frauds worth $580,000.
She claims he controlled everything.
It's alleged that in May 2008, Wright set up two Trade Me accounts and two bank accounts while living in Napier.
On May 27, 2008, a used plug-in spa was listed for sale with its listing saying it was needed to "help pay family medical bills".
A Dunedin woman won the auction and paid $4065 for the spa.
In an exchange of emails around getting the spa delivered, the seller said they were at Starship Hospital with a son on life support. The buyer offered her best wishes but the spa was never received – and she never heard from the seller again.
Another exchange involved a silage wagon and Suzuki quad bike sold for $16,500. When the items didn't arrive, the buyer phoned and spoke with a male who said they were at Starship with a nephew who had brain cancer.
A Kawasaki motorbike was allegedly sold three times, with stories around a sick son.
One witnesses today told how after buying the bike for $2650 he had a phone conversation with a woman called "Susan" and sympathised with her tale of a sick son with a brain tumour.
"As a father with a son the same age you get sucked along. It was a good game," the witness said.
They soon had concerns of a con and when they tried phoning back, got no answer.
They never got their money back.
Asked by defence counsel Elizabeth Bulger if the "woman" the witness spoke to on the phone could've been a man putting on a woman's voice, he laughed.
"Not a chance," he said, adding that the woman had a slight accent and might've been English.
Both Wright and Bennett were arrested as the pair sailed into Sydney Harbour after crossing the Tasman Sea from Northland on a crippled yacht in February 2015.
Wright was extradited from Australia to New Zealand in November 2018.
The trial, before Judge Paul Kellar, continues.
