Sorry, I still don't get under what authority is Patrick Murck allowed to receive, possess and transfer stolen goods? There must be some sort of judicial process which results in the granting of a warrant to do so? Please Patrick Murck, lets have all the facts and proof.
It's unlikely that there's going to be an issue regarding him receiving or holding the funds in trust. Where an issue potentially arises is the transferring of the funds to someone else and I'm sure that Patrick's going to do everything possible to protect himself from any potential liability in that respect.
As an interesting side note, if a NZ entity becomes insolvent and a creditor helps secure assets or uncover hidden ones, the creditor's costs associated with securing those assets become a preferential debt.
