The man allegedly behind threats to contaminate infant formula with the poison 1080 may end up before the High Court.
He faces two charges of blackmail but cannot be named for at least six months because of a suppression order.
Charging documents allege the action was financially motivated.
During a brief appearance in Manukau District Court today, the defendant's former counsel Hugh Leabourn was replaced by John Billington, QC.
Judge David Harvey said there had been some discussion about the matter being elevated to the High Court because of the seriousness of the allegations.
