Judge Pamela Andrews confirmed in court that the application was made on the grounds of Butler's "ill health".
The Crown did not oppose the application.
Outside court Crown prosecutor Brian Dickey said Butler's situation would be reviewed after February.
It is alleged that between 2004 and 2008, the defendants participated in unauthorised related-party lending totalling more than $20 million.
Dominion Finance Group (DFG) and North South Finance (NSF) were operating subsidiaries of the NZX-listed Dominion Finance Holdings (DFH). Both companies offered property and commercial loans.
DFG had been operating under various names since 1954 and was bought by Butler and his wife in 1987. It went into receivership in September 2008 and NSF went into receivership in July 2010.
DFH entered voluntary administration in October 2008 and was placed into liquidation in February 2009. In total, it is estimated the group owes creditors about $400m.
Butler declined to comment outside court.
