As for the likes of Seaguardian or similar, for long range maritime ISR, that's a separate project likely to be operated by the air force as part of a broader, in-service, capability to complement existing long range assets such as the P-8. Presume NZDF are looking at the RAAF's experience operating the MQ-4C to better inform the decision making process, so we'll have to wait and see.
Personally though, whilst such assets would undoubtably be beneficial for long endurance surveillance tasks, their survivability if contested could be called into question, therefore wonder if the better strategy would be to operate a small number of them but also seek additional manned craft such as P-8 which can to a reasonable extent defend itself (as well as better contribute to surface and sub-surface warfare). Mind you the recent P-8 acquisition notifications (eg for Singapore and others) seem to suggest the cost of the Poseidon has doubled ... well unless the cost includes extremely extensive support and training packages!
This announcement (Syos) is for further experimental drones for Army and Navy to further expand doctrine.
