Hogan would not reveal how much the assets are worth and suppression orders are in place about one of the properties.
The police's application for the restraining orders was filed last month and mentioned briefly before Justice Kit Toogood in the High Court Auckland this morning. The case is due to come back to the court later this month.
Assets associated with former C+M director Wayne Douglas - Nicholls partner-in-crime - have already been forfeited to the Crown and earlier this year police cut a deal with the owners of two properties linked to him.
The parties agreed a cheaper property linked to Douglas should be forfeited to the Crown and another almost three times the value not be targeted.
A profit forfeiture order was made in connection with a Whangaparaoa property which Douglas bought in 2008 and had a capital value of $560,000 as of 2011.
The deal meant that another property linked to Douglas with a capital value of $1.5 million was removed from the scope of police restraining orders.
Douglas is serving a jail term of eight years two months and was sentenced the same time as Nicholls.
