When Meehrtens was kidnapped by rebels from the West Papua National Liberation Army ( TPNPB) insurgent group, he was providing essential air links and supplies to remote communities.
His discharge came after Wellington and Jakarta made concerted diplomatic work.
After on Saturday, Faizal announced that the Indonesian work force may hold a press conference.
In exchange for his independence, the rebels had demanded that Indonesia grant him an apology.
A spokeswoman for the New Zealand Ministry of Foreign Affairs and Trade said it would make a remark at a later time.
A request for comment was never received by the TPNPB.

The TPNPB’s freedom fighters last month set fire to the Susi Air aircraft, released five additional travellers, and held on to Mehrtens.
During his months-long suffering in the Indonesian land, the New Zealander made occasional appearances on video, possibly under duress, to handle his family and his government.
In proof-of-life videos where he requested medication to help his asthma, the rebels claimed he was in excellent health throughout his confinement, but his look changed significantly as he got older, became haggard, long-haired, and had an unkempt hair.
