Two former Dominion Finance directors accused of misleading investors are applying to be discharged from the case.
Their trial is due to start later this month.
Dominion Finance and North South Finance directors Richard Bettle and Vance Arkinstall faces seven Securities Act charges for allegedly signing offer documents that contained untrue statements.
Another director, Paul Forsyth, is also facing charges.
The case against the men is being brought by the Financial Markets Authority - six of the failed companies' directors were originally facing charges but one has died and two others pleaded guilty.
