When there was a FSU, the FIR boundary I recall was in the vicinity of the island. I believe the FIR boundary was moved west to where it is now quite some years ago.
NF is now some 200NM inside the AK FIR, so the provision of services naturally rests with NZ. The island is Australian territory, but the airspace belongs to/is managed by NZ.
Someone in Airservices would be able to determine if there is a letter of agreement with NZ, and if it makes any mention of NF.
