The three directors on trial deny the charges against them. The case, brought by the Financial Markets Authority, began in October after numerous setbacks but is wrapping up.
During the trial the Crown has alleged that Bridgecorp's deteriorating financial health was not disclosed in the company's registered prospectuses.
The Crown has also alleged the directors failed to disclose that Barcroft - a company to which Bridgecorp sold loans worth $76 million - was a related party.
The Crown depicted the two companies as closely linked to each other and said Bridgecorp used Barcroft as its "treasury or piggybank".
By failing to inform investors of its relationship with Barcroft, Bridgecorp's financial position was painted as being "far more favourable than [was] the truth", the Crown said.
Justice Geoffrey Venning, who is hearing the trial alone, has indicated he will give his verdict on April 5.
That same week, former Bridgecorp director Gary Urwin is expected to be sentenced after a disputed fact hearing.
Urwin originally pleaded not guilty and appeared in court with Petricevic, Roest and Steigrad. But he changed his plea in November last year.
The charges carry a maximum penalty of five years' jail or a fine of up to $300,000.
Urwin's lawyer, David Reece, asked in November for a home detention report to be prepared, but prosecutor Brian Dickey said the Crown would seek a term of imprisonment.
Former Bridgecorp chairman Bruce Davidson was sentenced to nine months' home detention in October after changing his plea to guilty, and was ordered to pay $500,000 reparations and perform 200 hours of community work.
