That appears to be what will happen. The literature that I've seen (eg
http://www.beehive.govt.nz/sites/all/files/NH90FAQ31July.doc) states "up to four NH90s will be able to be transported aboard the new Navy, Multi Role Vessel", i.e. "transport" not "operate" (the Seasprite is tasked to "operate" from the MRV. Of course the NH90 could too, under some limitations such as sea state, as long as rotors are bolted/unbolted, probably not a very efficient method though).
Also see the NH90 website "main data"
http://www.nhindustries.com/site/FO/scripts/siteFO_contenu.php?arbo=3&noeu_id=10012&lang=EN
and compare the NH90 TTH without folding rotors
http://www.nhindustries.com/site/FO...php?lang=EN&noeud_id=10012&arbo=3&page_id=644
with the navalised NFH90 plan showing the folded rotors

I've always thought that perhaps NZ should be purchasing a few NFH90's dedicated to the MRV to allow them to operate from that vessel. The problem then is, is that a basic NFH90 for troop transport or the full deal with search radars and weapon systems etc? It's probably a cost we can't afford until perhaps the Govt thinks about replacing the Seasprites in the future.
