Helsby-Knight's trial is due to take place next September.
He appeared in the Auckland District Court near the end of 2012 after being arrested in Bangkok, where he had been based for the previous four years.
His Thai visa was cancelled and he returned back to New Zealand, denying the charges soon after his arrival.
Other aliases he is understood to go by include Foxconn GroupPlc, Michael Caughey, Mike Brandoff, Michael Kain, Michael Kuhn, Michael Maverick and Michael Wright.
After more than two years in custody, Helsby-Knight today made a fresh bid to be released on bail.
A lawyer representing him appeared in the High Court at Auckland this morning to appeal an earlier decision refusing bail.
The hearing, however, was adjourned until next month.
