The Court of Appeal is to hold a new hearing to discuss the upcoming retrial of former ACT Party leader and Auckland mayor John Banks.
Mr Banks was convicted in August of failing to declare two $25,000 donations from internet entrepreneur Kim Dotcom during his mayoralty campaign in 2010.
He took his case to the Court of Appeal, which overturned the conviction but ordered a retrial.
His legal team applied to recall the retrial judgement, leading to this new hearing.
Radio New Zealand has been told the application from Mr Banks concerns evidence not yet heard in court around an alleged secret meeting between Mr Banks and Mr Dotcom, and discussions about donations.
The Court of Appeal said the hearing would be on 28 April.
