It would be nice but why would Ardern do that for the NZ part of FVEY? Even though we're now out of FVEY there's absolutely no reason for the NZ GCSB to stop spying for the Cabal especially if Queenstown in the South Island of NZ is indeed a bolthole for the Elite.
Ardern and at least the previous three PMs have all been Cabal players and would also, I assume, still have clearances. Former NZ PM & UN Ms Helen Clark is also Ms Arderns mentor.
